How to rise to the very top?

From athletes like Simone Biles and Michael Phelps to scientists like Marie Curie and Albert Einstein, identifying exceptional talent is essential in the science of innovation. But how does talent originate? Did the most talented athletes, scientists, and musicians reach peak performance relatively early or late in their career? Did they forgo mastering multiple sports, academic subjects, and musical instruments to reach world-class performance in only one? In an Analytical Review, Güllich et al. looked at published research in science, music, chess, and sports and found two patterns: Exceptional young performers reached their peak quickly but narrowly mastered only one interest (e.g., one sport). By contrast, exceptional adults reached peak performance gradually with broader, multidisciplinary practice. However, elite programs are designed to nurture younger talent.

That is from a new article in Science by Arne GüllichMichael BarthDavid Z. Hambrick, and Brooke N. Macnamara.  Via Atta Tarki.  But are they conditioning on a collider?  Short players seem to do pretty well in today’s NBA…

Or more specifically Nenad TomaševMatija FranklinJulian JacobsSébastien Krier, and Simon Osindero:

AI safety and alignment research has predominantly been focused on methods for safeguarding individual AI systems, resting on the assumption of an eventual emergence of a monolithic Artificial General Intelligence (AGI). The alternative AGI emergence hypothesis, where general capability levels are first manifested through coordination in groups of sub-AGI individual agents with complementary skills and affordances, has received far less attention. Here we argue that this patchwork AGI hypothesis needs to be given serious consideration, and should inform the development of corresponding safeguards and mitigations. The rapid deployment of advanced AI agents with tool-use capabilities and the ability to communicate and coordinate makes this an urgent safety consideration. We therefore propose a framework for distributional AGI safety that moves beyond evaluating and aligning individual agents. This framework centers on the design and implementation of virtual agentic sandbox economies (impermeable or semi-permeable), where agent-to-agent transactions are governed by robust market mechanisms, coupled with appropriate auditability, reputation management, and oversight to mitigate collective risks.

Here is the link, this is some of the most important work of our time.  Here is the previous MR post on Krier.

Reading List 12/20/25

The Sagrada Familia under construction in 1906. Via Muse.

Welcome to the reading list, a weekly roundup of news and links related to buildings, infrastructure and industrial technology. This week we look at Tesla’s robotaxi crash reports, a fusion startup merger, the decline of US injection molding, Wyoming’s snow fences, and more. Roughly 2/3rds of the reading list is paywalled, so for full access become a paid subscriber.

TAE Technologies merges with Trump Media Group

Here’s a merger I didn’t see coming: TAE Technologies, one of the current crop of fusion energy startups (and one of the ones that has raised the most funding after Commonwealth Fusion) is, for some reason, merging with the Trump media group (the parent company of Truth Social). From the Financial Times ($):

The Trump family media group has agreed to combine with Google-backed fusion energy company TAE Technologies in a deal valued at $6bn, representing a bet on nuclear energy powering the artificial intelligence boom.

The all-stock deal will merge Trump Media & Technology Group’s access to capital with TAE’s fusion technology in an effort to meet the soaring power demands of AI, the two groups said on Thursday.

The unusual deal highlights the changing nature of dealmaking in America under US President Donald Trump. It brings together two industries rarely seen at the same table: Trump Media, built on right-leaning online politics, and a Google-backed fusion company rooted in Silicon Valley’s long bet on breakthrough energy tech.

The combined group plans to start construction in 2026 on what they described as the world’s first utility-scale fusion power plant. They initially plan a 50MW facility and later up to 500MW.

At Bloomberg, Matt Levine describes this as taking advantage of Trump Media’s ability to sell stock in the absence of anything resembling a profitable business:

…if the CEO of TMTG sat down with the CEO of a NUCLEAR FUSION COMPANY and got to talking about combining their businesses, a conversation like this would not make a ton of sense:

TMTG: We operate a social media site and we’re getting into anti-woke exchange-traded funds. Our mission is to “end Big Tech’s assault on free speech by opening up the Internet and giving people their voices back.”

Nuclear fusion company: Cool that sounds fun. We are working on smashing atoms into each other to generate power.

TMTG: Huh, we should team up. Maybe our social media site can give you tips on how to smash atoms, or we can cross-sell your electricity to our anti-woke ETF customers.

Nuclear fusion company: What.

Whereas a conversation like this has an obvious logic:

Nuclear fusion company: We do fusion stuff, we’ve raised $1.3 billion of capital from investors like Google and Chevron, but we need more money to build fusion power plants.

TMTG: Oh people love giving us money, we should get together.

Tesla crash reports

Data on the crash frequency of Waymos suggests that Waymos are much, much safer than human drivers (to the point that some people are calling for widespread adoption specifically as a public health measure). The same does not seem to be true for Tesla’s robotaxis. Via Electrek:

While a few fender benders might not seem like headline news, it becomes significant when you look at the math.

Last month, Tesla confirmed the fleet had traveled roughly 250,000 miles. With 7 reported crashes at the time, Tesla’s Robotaxi was crashing roughly once every 40,000 miles (extrapolating from the previously disclosed Robotaxi mileage).

For comparison, the average human driver in the US crashes about once every 500,000 miles.

This means Tesla’s “autonomous” vehicle, which is supposed to be the future of safety, is crashing 10x more often than a human driver.

While Tesla’s Robotaxi fleet reportedly increased in November, with the number of cars spotted going up to 29, there’s no evidence that the Robotaxi mileage increased. In fact, the utilization rate indicates Tesla is running only a few vehicles at a time – meaning that mileage might have actually gone down.

Electrek’s data for human crash frequency seems to be wrong — per AAA analysis of US DOT data, it seems to be closer to around one crash per 100,000-200,000 miles or so — but Tesla still seems worse than human drivers.

iRobot declares bankruptcy

I once chatted with someone considering founding a robot startup who said that the challenge with robots is that it’s hard to get to a huge market with many millions of potential customers. They pointed to iRobot as one of the only robotics companies that had tapped into a really huge market, with robotic vacuums. So it’s noteworthy to me that iRobot is now declaring bankruptcy. Via Bloomberg:

iRobot Corp., the company that revolutionized robot vacuum cleaners in the early 2000s with its Roomba model, filed for bankruptcy and proposed handing over control to its main Chinese supplier.

The Massachusetts-based consumer robot maker, which is currently listed, will be taken over by China’s Shenzhen PICEA Robotics Co. and a subsidiary of the Chinese firm, according to a press release. The company listed between $100 million and $500 million of assets and liabilities in a filing.

The common stock of iRobot, founded in 1990 by engineers from the Massachusetts Institute of Technology, will be wiped out under the proposed Chapter 11 plan filed in Delaware on Sunday.

Shares of the company plunged as much as 75% on Monday, hitting an all-time low.

iRobot enjoyed initial success with the Roomba that it debuted in 2002 and which quickly became synonymous with autonomous vacuum cleaners. But earnings at the firm, which has sold more than 40 million home robots, began to decline in the post-Covid era, hit by supply chain issues and cheaper competitors. The firm warned of potential bankruptcy earlier this month.

In 2022, Amazon.com made an offer that would have turned the company’s fortunes, but it collapsed over a clash with European Union competition authorities.

IEEE Spectrum has a good interview with the former co-founder of the company here.

Bloomberg notes that the merger with Amazon fell apart due to EU issues, but the merger was also opposed by US politicians, which folks have not been shy about pointing out. Via a Reason article from October:

Online retail giant Amazon announced in August 2022 that it had agreed to purchase iRobot, makers of Roomba robot vacuums, for $1.65 billion. The acquisition would expand Amazon’s footprint in the smart home market, after it previously purchased video doorbell company Ring.

The following month, the Federal Trade Commission (FTC) opened an investigation into the merger. Sen. Elizabeth Warren (D–Mass.) and several Democrats in the House of Representatives sent a letter to then-FTC Chair Lina Khan, saying “the FTC should use its authority to oppose the Amazon–iRobot transaction.”

Rubber couplings

One of the recurring themes of my book is the corrosive effects of variability on a production process. Variation in a production process means waste — parts that are outside of tolerance and need to be thrown away or reworked, buffers of material that accumulate between misaligned process steps, and so on.

One strategy I highlight for dealing with variability is to make your process more robust to it, such as by redesigning a part or assembly to allow for larger tolerances. Here’s an interesting example of something like this being used in practice: rubber couplings between machines to allow for shafts that are slightly misaligned.

Parts company McMaster-Carr has thousands of flexible couplings for sale, though these mostly don’t look like rubber bands. Alignment laser system manufacturer Ludeca has a bit more on flexible couplings, recommending (unsurprisingly) that machines only be run temporarily in misaligned conditions:

Some coupling manufacturers will sell couplings claiming that the coupling can take shaft misalignment. While this is true for most flexible couplings, it can be easily misinterpreted. Flexible couplings are designed to withstand, without damage, some shaft misalignment. Sometimes it is perceived that, since the coupling can take the misalignment, the machines can run under this condition without any consequences. When running machinery with significant shaft misalignment, bearing and seal life may decrease immensely, and other damage results. Therefore, for longer machinery life, it is always recommended to have equipment laser aligned to standard industry tolerances for shaft alignment, and not to the looser alignment tolerances allowed by the coupling itself.

Revenge of the Dilettantes

Last year I decided to stop doing annual roundups of all my writing, so for the second year in a row here is my gift to you — no annual roundup. You can scroll the archives if you actually want a list of what I wrote or slopped about.

The lighthouse handcrafted post of the year was probably The Gramsci Gap from January 10, and the lighthouse sloptraption was probably Configurancy from Dec 11, the first of my posts that I think I could not have written any version of, without AI assistance. ChatGPT contributed on all fronts — knowledge, ideas, and even to my signature move, naming the focal new concept.

The dates of those two bookend lighthouse posts alone tell you the story of the year. In 2025, Contraptions itself became a contraption. A monstrous contraption. Monsters, first encountered in The Gramsci Gap, increasingly took over my imagination and eventually led to my new motto: Be Slightly Monstrous. This is now the governing ethos of what is now less a newsletter and more an AI-scaffolded workshop, study group, and centaur-social-network of sorts. It’s only going to get more monstrous from here on out.

All my friends are now all-in on transforming themselves into AI-augmented transhuman monsters who read, write, make, think, and socialize with AI intimately in the loop. There isn’t even much schadenfreude to be found in the antics of frantic humanists in cope mode. Better spectacles abound.

This new phase demands new rules of engagement, so let me get that out of the way before continuing with what’s going to be a wild riff on many matters.

Going forward, I will not be paywalling any of my writing. You can still be a much-appreciated paid subscriber, but the only thing that will affect is ability to comment on articles.

I’m also slowly going back and unpaywalling all my archives (it’s slow since Substack doesn’t offer a bulk unpaywall mechanism).

If you’re pushing up against the limits of your newsletter budget, feel free to go unpaid. If you choose to stay on the paid tier, thank you 🫡.

There are some Substack-specific reasons I’m doing this (more at end), but the main reason has nothing to do with Substack — it is now obvious that barring catastrophic AI-bubble-popping, all my future creative shenanigans will be heavily shaped by AI use, misuse, and abuse, and necessarily, many will take shape in more AI-native media rather than this mildly AI-hostile one.

So I’m going to start using Substack more in the way it already wants to be used anyway — as a place to report on activities with centers-of-gravity elsewhere (true “newsletter”), and join conversations with other writers.

There will still be essays here of course, but they’re probably going to have a different, more workshop-notebook/release notes type energy.

Notes on Writing

Much of my writing energy and attention this year actually flowed towards getting the magazine off the ground, along with and .

It’s been an amazing opportunity for me to channel the spirit of John W. Campbell of Astounding fame, and try and meme the genre of Protocol Fiction into existence. Through three contests and dozens of published short stories, we’ve spun up a solid cabal of a dozen odd writers (all filtered for radical AI-positivity of course) now pushing the boundaries of that project.

While much of the energy that’s gone towards Protocolized has been in the editorial vision-setting and direction department, I’ve also been writing there. My most substantial piece of the year was probably the one I published in Protocolized in January — Strange New Rules (hand-written). But my favorite piece of the year, also in Protocolized, was The Signal Under Innsmouth, an AI-assisted transposition of a classic Lovecraft story to an AI-transhumanism register.

Protocolized will continue to be a big part of my presence here on Substack next year.

As an aside, for some reason, these days I find it easier to write for publications other than my own. Two other pieces I was very happy with were the introduction to The Protocol Reader, and a preface for a friend’s book that I’ll be able to share next year.

There’s more going on with my writing that is making me reconsider how and where I do it. Over the last 6 years that I’ve been on Substack, I’ve been very slowly serializing a book, as well as developing several other serialized projects. Even before the rapid maturation of AI tools for writing, these were never quite a comfortable fit for Substack.

I plan to move these serialized projects (or at least, the ones I intend to finish) off Substack and into more book-like AI-assisted production and publishing workflows. If I ever finish my book, it’s definitely going to get done with AI assistance and get published online-first in an AI-forward way. Right now, LLMs aren’t quite good enough to work on book-length things, but they’re getting close. They’re more than good enough to help rig custom workflows and do supporting backend research though.

Two projects I’ve been procrastinating on for ever went from zero to nearly done in mere days thanks to AI — the Yakverse Chronicles, which is now published as a rough cut online, and a book based on my Twitter archives (150k tweets and hundreds of threads to filter, select from, and clean up), which is 90% done and will be published online in January.

What’s notable about both projects, but especially the latter, is that they are the results of completely bespoke, even idiosyncratic workflows, and sui generis publishing solutions. What had me stalled previously was that no off-the-shelf tool could easily produce online books the way I wanted: With minimal infrastructure and maintenance needs. So a fat AI workflow leading to a lean output, such as a static html site, was ideal. I don’t need either my development workflow, or my content architecture, to be reproducible, repeatable, or scalable either horizontally or vertically. N=1 solutions are fine.

In the case of the Twitter book, transforming and formatting tweet content into a roughly book-shaped static html artifact was simply beyond the capabilities of any standard publishing workflow short of brute force manual labor. One does not simply print tweets.

I have an even bigger project ahead — getting my retired blog Ribbonfarm off expensive WordPress hosting and porting it to some sort of customized low-cost, zero-maintenance, high-longevity memorial/archival hosting solution.

There is a bigger theme in the direction all my writing and writing-scaffolding projects, from shitpost-scale to book-scale, are tending.

Bespokeness

If you’re wondering “what comes next for publishing” after the late-blogging Substack-enclosure era, it’s not a single new publishing paradigm, “alt” coded substitute platforms like Ghost, or alt techno-political publishing paradigms like decentralized publishing on IPFS.

The future is bespokeness.

There is no reason anymore to force-fit content into standardized containers besides convenience.

The marginal cost of making a custom workflow and publishing solution for your idea is now low enough, it’s a serious alternative to what we’ve been doing for centuries — making the content conform to the constraints of production, publishing, and distribution media. AI allows us to make things that look more like illuminated manuscripts than books.

What happened to marketing a decade ago is now happening to publishing. The message is becoming the medium (the link is to a blog post about a couple of talks I did in 2014, about this inversion triggered by intelligent computation capabilities).

Now, there’s no reason to go nuts with idiosyncratic publishing solutions for bog-standard essays simply because you can, but also… there’s no reason not to when you have an idea that would otherwise call for medium-driven compromises. For example, I don’t like how Substack doesn’t allow text or image centering. Well, now if I want that, I don’t have to spin up a high-maintenance SSG site or use a heavyweight CMS. I can just vibecode a one-pager site exactly the way I want. In green Comic Sans font too if I want.

As someone pointed out somewhere, one interesting effect of this is that registering a domain just to serve a single custom-formatted essay is now a meaningful option at scale. If you have money to spare, you can just spin up a new site for each new essay, and each can be a unique work of art if you want.

In a few years, you might even be able to define a meta workflow where an AI designs bespoke distribution artifacts for each essay based on creative design rules you specify. It’s now less about AI getting more capable, and more about AI continuing to get too cheap to meter along the current trajectory. The capabilities are already there.

Writing as a sequence of art-gallery like singleton essay sites is probably overkill and would cause brand/marketing problems, but the point is — the future is bespokeness. It’s going to look like the wild and crazy era of Geocities webpages again. Even extreme n=1 futures are possible, where no two sites will look the same or get published the same way. It will be gloriously ugly and all the font mavens will be sad.

After all, n=1 production at scale is the way nature operates, and nature does fine without economies of scale. Intelligence is how you get on diminishing cost curves without surrendering to uniformity and monocultures. If the solution is good enough for nature, it’s good enough for me.

Economies of variety, which I’ve been lusting after for a decade, are finally here for real.

What this means: You can expect to see my writing here continue to get more AI-transformed, and the focus to shift partly to longer projects, some of which will take shape off Substack within bespoke snowflake publishing solutions.

Art, Code, and Robots

The idea that the future is n=1 bespokeness has even bigger implications for creative work outside of writing.

Much of my creative energy in 2025 hasn’t been devoted to writing at all, especially in recent months. You could say 2025 is the year I finally admitted to myself, at age 51, that I’m not primarily a writer and never have been. I’m primarily a medium-agnostic dilettante idea guy in need of skilled serfs to implement my ideas in whatever medium is appropriate for each.

Well, I have my jinn-like superserf now. So do you. We can all be Alladins now. If we want to be. I do. Rubbing magic lamps over painfully honing crafts any day for me.

In the last couple of months, I made my first serious foray into art in decades. Back in high school, I was at least as into drawing and painting as I was into writing. But though I have always had decent visual ideas and composition instincts, I was never quite good enough at the craft side of it to get very far on execution. It takes me a long time to make even passably decent art by hand. This fairly basic and marginally competent realist drawing took me probably 3x the time to make (circa 2006 I think) than it would someone with more aptitude. And while I did (and do) enjoy the time spent in ludic immersion with a pencil, sometimes you just want to get to the finished product. Sometimes it’s not about the journey. It would take an image generator 10 seconds to do better than this of course.

Elephant, made in an art class in 2006

As a result of my artistic limitations, and as you’ll know if you’ve been reading me for a while, I’ve mostly contented myself with crude cartoons, maps, and diagrams to accompany my writing, and collaborated with more talented and skilled artists where I’ve been able (and higher artistic quality has been called for).

The emergence of AI assistance first inspired me to get back into handmade art more seriously, which then led on to my first non-trivial experiment in generated art. You can read about that in Bucket Art from last week.

I continue to be delighted by my ability to simply wave a wand and instantly create new artworks, in what feels like a very personal style, for pennies.

Helicopter 1, made with my Bucket Art model on Titles.xyz

The red helicopter motif, by the way, which has been my stable pfp for several years now, was originally generated by a friend with Dalle2, based on my then-pfp of the standard helicopter emoji 🚁. My identity is now unreasonably indexed to an emoji that has now been through a few generations of AI transformations.

The publishing solution for the Bucket Art project, of course, is a hideously bespoke contraption comprising a vibe-coded single-page site, a hosted AI model, and an NFT collection. This is what it means to be slightly monstrous. Doing things like this.

More recently, I’ve finally gotten seriously into vibecoding. You’ve already seen a couple of early results: The gallery page for Bucket Art, and the updated Art of Gig site now featuring the online Yakverse Chronicles book. Both were vibe-coded without me having to touch a single line of code. Both are projects that previously I would have paid someone to do, or more likely, simply abandoned.

For my Twitter archives online book, which is a massively more complex project, I’ve already generated and used more code (github repo here) than I hand-wrote in my entire past life as a pre-AI engineer. The code is a mess, but it only needs to work once, and is cheap to produce.

I’ll publish that Twitter book (a compilation of my best tweets and threads) in a couple of weeks, and work on making it a paper book too. It’s been the sort of heavy duty data laundering pipeline project for which I’d previously have had to hire a data-science contractor.

My true white whale though, is robotics. I’ve been dabbling at the edge of my dilettante abilities for a few years now, along with my buddies at the Yak Collective, but AI tooling beyond text/images/code is finally starting to get good enough that I can do more than I ever thought I could. So I’m hoping to do a lot more with my robots in 2026.

I last did serious hands-on technical work around 2007-08, and back then I always chafed at my engineering skills not being good enough to execute on my much better engineering ideas, and having to rely on others as a result. Now that constraint is increasingly dissolving, at least at the level of the sort of prototype-scale n=1 one things I like to build.

And beyond these separate categories, who knows?

Some of the projects I’m now idly dreaming of doing would require combining writing, art, code, and hardware engineering. I don’t have any more spare time in the evenings and weekends than I used to. But I can now do a lot more in the hours I have, without needing to turn into a full-stack genius-god overnight.

What all this means — you can expect to see relatively more reports of art projects, vibe-coding projects, and robotics projects in this newsletter.

Full-Stack Dilettante Futures

Routinely reaching well beyond my native creative aptitudes is a heady feeling. Apparently, I’ve always-already been an artist/programmer/roboticist etc. It’s just that previously you had to be some sort of full-stack genius-god on the aptitudes front to express such a personality.

Now you can just invoke a full-stack-genius-god jinn to complete your natural personality for $20/month.

It’s genuinely hard, depressing, and boring to think of myself as primarily a writer now. With AI prosthetics, my natural dilettante tendencies are finding pathways for expression that simply didn’t exist before, and it is becoming clear that temperamentally, I tend towards a breadth that demands full-stack depth for realization.

This train of thought inspired a bon mot recently — a man’s reach should exceed his grasp, else what’s vibecoding for?

Before AI, writing just happened to be the only mode of creative expression I could access at low-enough cost, and without AI, given my mix of actual aptitudes and energy levels.

Looking back, in high school, I was something like the Jason Schwartzman character Max in Rushmore. Frenetically dabbling in a dozen different hobbies, from astronomy and airplanes to writing and theater, pursued with dilettantish vigor and amateurishness.

This is not a mode of being you can keep up as an adult unless you have a trust fund underwriting your life. You have to identify your best aptitudes (or in my case, my least worst ones), focus, and do your best to make a living with or near them. You have to do that “hone your craft” thing so many tedious people seem to fetishize, and which I find to be mostly hell on earth.

I’ve spent most of my life just looking for the best leverage I can find for my minimally, reluctantly honed amateur tendencies. This mostly meant gravitating to n=1 margins with so little competition, low-craft amateurishness was never the issue.

Now the jinn-tooling is gravitating to the margins too, where us dilettantes have already been camped out all our lives.

It’s time for a revenge of the dilettantes. The self-consciously deep types are going to hate it. We’re poised to take over the world, one bespoke n=1 janky contraption at a time, conjured up with the help of genius-god full-stack jinns who don’t skeptically challenge even our dumbest, shallowest ideas.

The Book Club

The highlight of the year was not any piece of writing or even non-written creative project, with or without AI. It was reading with AI.

The Contraptions Book Club, the first book club I’ve ever run, was a big success. Some thirty-odd people joined me in reading a dozen books, one a month, plus a whole bunch of side reads.

It may not be immediately obvious how AI affects a book club, but it did. Not only were at least a third of the picks AI-assisted picks (found by exploring bunny trails in search of good reads), many would not have been readable at all without an AI assistant on hand.

From translating bits of Latin or Greek in books like Giordano Bruno in the Hermetic Tradition that would otherwise have been beyond me, to exploring the dozens of obscure historical side quests sparked by each book, AI suffused every aspect of the reading process. I tackled books I would previously have set aside as too dense and scholarly to take on. So did the others in the book club.

One of the more subtle affordances of AI in the reading loop was the ability to sustain exploration of an overarching grand thesis — that modernity began much earlier than people think, around 1200 rather than around 1600.

This is the sort of ambitious thematic focus that requires not only a good deal of curation and choreography in picking the books and leading the discussions, but really only feels substantial if you can go beyond casual reading to something that resembles studying and research.

It was clear from the discussions that all the regulars were using LLMs to read around the books as much as they read through them. Not quite the same thing as close reading in the academic or scholarly sense, but something that feels perhaps more powerful. Perhaps we should call it thick reading, by analogy to thick description in anthropology. Or dense reading. I think, for every word I read in the actual books, I probably read two words in a related LLM chat.

For the actual contents of the book club, I’ve written two posts The Modernity Machine and The Modernity Machine II. I’ll do a third part soon and make a trilogy of it.

We’ll be doing a book club in 2026 too. Stay tuned for details.

The Studious Dilettante

The AI-assisted reading —> studying phase shift is even more pronounced when it comes to short-form reading (essays and papers).

For several years now, much of my free time has been structured by participation in weekly or biweekly study groups. I’m now regularly part of four such groups, and occasionally drop in on three more. The structure in each case is similar — we read for 20 minutes, then discuss for 40 minutes. Before AI, the structure meant you could at most tackle a long essay or short/simple paper. Now with AI, we often get through 2-3 dense papers or reports in a single session. There is a skill to this that can be learned and, uhh… honed.

While I’ve always been a serious reader, I’ve never been able to match the truly heavy readers in terms of volume, depth, or speed. My reading exploits, as with my creative exploits, have always been on the dilettantish side.

The idea of a studious dilettante seems like an oxymoron, but with AI in the loop, it needn’t be. AIs can do the studious part.

The trick is to find a way to rein in the the runaway chain reaction that can happen when you close the loop between idle curiosity and a jinn who either knows everything about, or will diligently think through, any idle shitposty thought that crosses your mind. The best way to do that is to form study groups with other humans, and focus on a stream of relatively dense but short texts at a steady tempo over months and years.

Humans can hold each other accountable for staying on topic in ways AIs cannot, because most of us care what other humans think of us, but most of us currently don’t care what AIs think of us. Because we suspect (correctly in my opinion) that AIs currently don’t “see us” in any manner resembling being seen by other humans at all.

But AIs can help our reach exceed our grasp, even as other humans keep us on track and on topic.

Many of my sloptraptions this year have in fact been something like private study and brainstorming notes. The sort of thing that in the past would likely have stayed in my private notebooks. With AI, study notes can easily level up to being usefully shareable artifacts. Cognitive dark matter becoming visible.

Somebody recently asked me if I try to make AI sound like myself in my sloptraptions. I don’t, partly because that would be a pain (training it on my writing is currently still a painful prospect), but mainly because much of my AI use isn’t writing so much as internal processing. My inner thought processes don’t resemble how I write, so there’s no reason to make my inner-thoughts sparring partner sound like that.

Whither Substack?

Over the past year, Substack has transformed to be more a social network of writers than a publishing platform (or as someone vividly put it, a farmer’s market of writers most of whom are engaged in keeping each other’s spirits up by buying each other’s wares).

Unless you want to fight the message of the medium, the best way to write on Substack is to collaborate and compete with other writers on themes that attract a critical mass of shared interest, while trying not to get sucked into the obsessively self-involved community dynamics, mimetic envy gyres, or attention-cornering headline themes.

There are sketchy leaderboards, badges (I got downgraded this year from solid-orange bestseller to mere outline-orange pleb), niches coalescing into mini taste-subcultures, angst and cynicism about the platform, communities of practice around gaming its incentives for profit, engagement farming playbooks being circulated, and all the other phenomena we’ve gotten used to over several generations of social media platforms.

On a timeline where AI hadn’t emerged, I would care about all this. Despite it being the tenth such platform trajectory to play out in exactly the same way.

In this timeline, where AI has emerged, I honestly can’t bring myself to care about any of it. To stress and extend that old joke, if you’re offered a seat on a rocketship, it’s dumb to argue about which seat on the horse-drawn buggy headed away from the launchpad has the best view.

Substack today features all the sound and fury signifying nothing that typically marks a cultural endgame slowly having the vitality sucked out of it because it rejects the most vital part of the future. Not least because the median writer on here reflexively hates AI. And of course, also because the team behind the platform has always exhibited a somewhat nostalgic design sensibility in their stewardship of the platform, focused more on revivifying the forgotten glories of old media than pioneering the mechanics of new media. They’ve already retreated from advances made by the blogosphere a decade ago, so it would be unreasonable to expect them to bet the farm on AI advances yet to be made. Maybe they’ll prove me wrong, but I’m not expecting much by way of Substack becoming an AI-forward platform. Not that I blame them. If they tried anything remotely ambitious, they would face a huge revolt from their core publisher audience.

The future, as I have noted, for reasons having nothing to do with Substack, is about AI-powered bespokeness and variety in the media landscape. In both form and content. It’s not going to come here. If you’re interested in it, you have to go elsewhere to seek it out.

That said, Substack is still a great place to host a basic newsletter, rig up some no-worries payment plumbing to make some money, and stay in touch with other writers you want to track or be tracked by. It’s a publishing Schelling point, enabled by the less-than-ideal commons-enclosing mechanism of paywall culture. It is not a publishing frontier. This is the place to be because this is the place to be. Nothing more, nothing less. So I’ll remain here while that remains true.

But it is already not the place where any sort of interesting creative future is unfolding. There’s merely a past winding its way (hopefully with some grace and humor) to some sort of respectable denouement. A gated retirement community for an entire civilizational cultural mood.

Which means, increasingly, this is not where my attention will be, but for the forseeable future, it is going to remain the easiest place to tell you about where my attention has been. So more posts are going to sound like Dispatches from Elsewhere.

So, I’ll see you in 2026 with more AI shenanigans, more book-clubbing, more monstrousness, and more Dispatches from Elsewhere.

Happy holidays!

Astronauts, launch teams practice Artemis 2 countdown

In a prelude to the real deal, the four astronauts of the Artemis 2 mission boarded their Orion spacecraft inside the Vehicle Assembly Building at the Kennedy Space Center on Saturday afternoon.

The three Americans and one Canadian participated in a launch day rehearsal referred to as the countdown demonstration test or CDDT. It was the first opportunity for everyone involved with the mission to be on hand and to go through the motions of the big day with the fully integrated rocket in the loop, instead of just data simulations. The test appeared to reach its conclusion with a cutoff of the simulated countdown at the T-29 seconds point at 5:51 p.m. EST (2251 UTC).

Astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen departed the Neil Armstrong Operations and Checkout Building at around 12:20 p.m. EST (1720 UTC), sporting their orange pressure suits, for a 5.5-mile journey to the Vehicle Assembly Building where the Space Launch System rocket and their Orion Capsule was waiting for them. After a few minutes of remarks to stand-ins for their family members and other NASA officials gathered outside, the crew boarded their transport vehicle and hit the road.

Originally, the astronauts were to be driven in new electric vehicles from a company called Canoo Technologies. However, that company went bankrupt earlier this year and according to a NASA statement to Spectrum News 13, in October, the agency instead leased Boeing’s Astrovan — used to transport astronauts for CST-100 Starliner missions — to serve as the transport vehicle.

The crew departed the building about three hours later than planned. A NASA spokesperson blamed the delay on communications issues, but could provide no further details other than that the issues were resolved and the test proceed.

The rehearsal is already running at least a month behind schedule. It was scheduled for November 19 but NASA postponed that, eventually blaming “a blemish” on a thermal barrier surrounding the Orion crew access hatch which prevented its closure.

The test was rescheduled for Dec. 17, but that too was  abruptly delayed without explanation.

The CDDT is similar to the terminal countdown demonstration tests performed during the space shuttle era. Those launch day rehearsals were done at the pad as they are for SpaceX Crew Dragon missions.

During an Artemis 2 briefing in September, Artemis Launch Director Charlie Blackwell-Thompson said after the crew enters the Orion capsule, they will perform a communications check, strap in, configure the crew module and proceed with the countdown to just before the terminal count before a planned stop.

“As part of that, we’ll also do an egress demonstration and that will be what we call CDDT part one,” Blackwell-Thompson said. “Once that testing is complete, we have some other servicing ops that we’ll take care of in the Vehicle Assembly Building.

“We will go ahead and do our flight termination system test and we’ll start closing out the vehicle compartments as part of our final closeouts of SLS.”

The timing of the rollout of the SLS rocket and Orion spacecraft will be contingent on a smooth CDDT and FTST. The rocket will be travel about four miles from the VAB to the pad at Launch Complex 39B.

The second part of the CDDT will happen shortly after the rocket gets to the pad. Blackwell-Thompson said they’ll use that time to review the emergency egress system, which is a zipline style basket system to get away from the rocket before the launch escape system is armed.

After some additional work, like doing some communications testing at the pad, the astronauts will be brought to the pad to run through the process of using the emergency egress system.

Once all of that is done, the stage will be set for the wet dress rehearsal, where teams will practice loading the SLS rocket with more than 730,000 gallons of liquid oxygen and liquid hydrogen.

The launch of Artemis 2 is currently slated for no earlier than February 6. NASA also says the launch will take place no later than April 2026.

So to the office, and thence with Mr. Coventry in his coach to St. James’s, with great content and pride to see him treat me so friendly; and dined with him, and so to White Hall together; where we met upon the Tangier Commission, and discoursed many things thereon; but little will be done before my Lord Rutherford comes there, as to the fortification or Mole.

That done, my Lord Sandwich and I walked together a good while in the Matted Gallery, he acquainting me with his late enquiries into the Wardrobe business to his content; and tells me how things stand. And that the first year was worth about 3000l. to him, and the next about as much; so that at this day, if he were paid, it will be worth about 7000l. to him. But it contents me above all things to see him trust me as his confidant: so I bid him good night, he being to go into the country, to keep his Christmas, on Monday next.

So by coach home and to my office, being post night, and then home and to bed.

Thanks, Suze! Abrego Garcia Seizes On Vanity Fair Interview

It was pretty obvious that White House chief of staff Susie Wiles’ admission to Vanity Fair that President Trump was engaged in “score settling” was going to make it into a legal filing sooner or later. Now it has.

In a filing overnight, Kilmar Abrego Garcia’s attorneys cited the Wiles interview as part of their bid to dismiss the indictment against him on vindictive prosecution grounds:

As a practical matter, we can say that of course it’s a vindictive prosecution. But as a legal matter, the standard to establish vindictive prosecution is high and hard to meet. Wiles’ comments alone won’t do the trick, but they are the capper to what has been a series of remarkable public commentaries, threats, and admissions about Abrego Garcia and his criminal case from high-ranking administration officials, chief among them Deputy Attorney General Todd Blanche.

The new filing, in addition to citing Wiles, reveals quite a bit more than we’ve known about recent proceedings in the Tennessee case, which have been taking place under seal and outside of public view for the past few weeks. Without getting too deep into the weeds, the judge in October found “a realistic likelihood of vindictiveness” and allowed Abrego Garcia to conduct discovery into the Trump DOJ’s conduct. That was a huge win and a major initial hurdle for any criminal defendant to overcome.

Since then, the Trump DOJ has fought tooth and nail to avoid having to comply with both the court order and Abrego Garcia’s discovery requests. It has repeatedly attempted to re-litigate the federal judge’s decision to allow discovery. It has stonewalled on providing responsive documents. It has attempted to quash Abrego Garcia’s subpoenas seeking live testimony from Blanche, associate deputy attorney general Aakash Singh, and acting principal associate deputy attorney James McHenry.

While the fight over discovery into vindictive prosecution has been mostly conducted behind closed doors, we can piece together a few things from the latest heavily-redacted filing:

  • DOJ, on orders from the judge, eventually coughed up “20-odd pages” of internal documents which Abrego Garcia now claims expose a “web of false representations to the Court” that Nashville acting U.S. Attorney Robert McGuire independently brought the case on his own, not at the behest of Main Justice (or the White House):

[W]hat we do know, from documents the defense and the Court had to pry out of the government’s hands, is that the government deceived the Court, the defense, and the public about Mr. McGuire’s purported status as the sole decisionmaker. Put bluntly, numerous government lawyers chose to mislead this Court in order to try to save this unjust prosecution.

  • The internal documents show that Associate Deputy Attorney General Aakash Singh was the conduit between Blanche’s office and McGuire, Abrego Garcia’s attorneys argue. Because the relevant documents and court rulings are sealed, we can’t independently verify the claims by Abrego Garcia’s attorneys, but let’s just say the redacted portions of their latest filing are pretty tantalizing:

  • We may not have to take Abrego Garcia’s attorneys’ word for it entirely. While they cite to a sealed Dec. 3 order in the case from U.S. District Waverly D. Crenshaw Jr. a total of 13 times in the new filing, they redact what Crenshaw said in the order – except in one place. In a possible redacting oversight, they appear to quote the judge as saying in his order that Singh had a “leading role in the government’s decision to prosecute”:

Despite the government’s brazen efforts to mislead the Court, the answer to this question is now obvious: this case landed on Mr. McGuire’s desk because Mr. Blanche’s deputy, Mr. Singh, who we now know had a “leading role in the government’s decision to prosecute,” placed it there. (Dkt. 241 at 5)

Where does this leave us?

Big picture: Abrego Garcia argues that the evidence of vindictive prosecution is so strong that the burden now falls on the government to prove otherwise and since the government won’t produce documents or witnesses to rebut the vindictive prosecution claim, the case should be dismissed.

Smaller picture: If the judge won’t dismiss the case now, then in the alternative Abrego Garcia wants him to deny the Trump DOJ motion to quash the subpoenas and proceed to an evidentiary hearing on the vindictive prosecution claim where top officials will be forced to testify.

One additional note: Abrego Garcia’s attorney filed a separate motion late Friday seeking sanctions against CBP commander Gregory Bovino for comments he made to national news outlets calling Abrego Garcia an “alien smuggler,” a “wife beater,” and an “MS-13 gang member.” Bovino also attacked the judges in Abrego Garcia’s criminal and civil cases as “activist” and “extremist.”

Bovino’s public vilification of Abrego Garcia came after Judge Crenshaw had already issued a series of orders to clamp down on prejudicial out-of-court statements by the Trump administration in violation of court rules. In one such order, Crenshaw previously directed the administration to provide actual notice of his order barring extrajudicial statements directly to DHS employees involved with the Abrego Garcia case and those who are authorized to speak on DHS’ behalf.

Given Bovino’s comments, Abrego Garcia is seeking sanctions against the government, but first he wants the court to inquire into how this happened:

Before the Court can determine what sanctions are appropriate here, however, the government should be directed to disclose to the defense and the Court whether and how the prosecution provided Mr. Bovino with a copy of this Court’s Order, who gave Mr. Bovino authorization to speak about Mr. Abrego’s case and what guidance Mr. Bovino was given about those statements, and any and all communications between counsel for the government and Mr. Bovino or DHS regarding Mr. Bovino’s statements, including any attempts to obtain a retraction or apology.

That gets you fully up to speed on what has been a slow-moving case. I expect that most of the sealed proceedings and filings will made public sooner than later, at which point we’ll have a finer-grained understanding of the discovery fight, what the administration has revealed and continues to try to conceal, and where Judge Crenshaw has come down on the key issues. But the latest filing is the best window into this case that we’ve had in a few weeks.

★ Apple Announces Changes to iOS in Japan for Compliance With the Mobile Software Competition Act

Chance Miller, reporting for 9to5Mac this week:

To comply with the Mobile Software Competition Act (MSCA), Apple has announced a set of major changes to the App Store and iPhone in Japan. The changes include new app distribution options for developers and new alternative payment rules for the App Store.

Apple announced the changes in a post on Apple Newsroom today and on its developer website. The company says that Japan’s “MSCA’s requirements for alternative app marketplaces and app payments open new avenues for malware, fraud and scams, and privacy and security risks.” Nonetheless, the company has collaborated with Japanese regulators to strike as best a balance as possible to comply with the law and protect users.

Broadly speaking, Apple says Japan’s MSCA does a better job of balancing openness with security and user protection than the DMA in the EU. For example, Apple does not have to support app downloads from the web in Japan like it does under the DMA. Apple retains ability to protect users from malware and other security risks. This is especially true when it comes to protecting children, as outlined below.

Developers in Japan can now offer their own payment processing within their apps and games, and offer link-outs to the web, but these options must be offered alongside the option to pay using Apple’s own in-app purchase system. Developers are allowed to offer lower prices in alternative payment methods. That strikes me as a decent, but not ideal balance. I think it’s fair for Apple to mandate that its own IAP be offered alongside any form of alternative payment within an app. But, as I’ve long advocated, links to the web — leaving the app for the system’s default browser — should be permitted without having to offer IAP too. But overall, where Japan landed is reasonable.

From Juli Clover’s report on Apple’s MSCA compliance at MacRumors:

Here’s a quick rundown of what’s changing as of today:

  • Side Button — Users in Japan will be able to change what the side button does, and it will be able to activate third-party voice assistants instead of Siri.
  • Payment options — Developers can offer in-app purchases, accept third-party payments in their apps, or direct users to a website to make a purchase.
  • Alternative app marketplaces — Apps can be distributed through alternative app marketplaces instead of the App Store. Users can set an alternative app marketplace as their default marketplace instead of the App Store.
  • Fee changes — New fees range from 5% to 26% depending on distribution method and payment method.
  • Browser choice — Users are prompted to select a default browser at setup.
  • Search engine choice — Users are prompted to choose a default Search engine at setup.
  • Navigation apps — Users in Japan can select a different navigation app.

Apple, in its own announcement, asserted its disagreement:

The MSCA’s requirements for alternative app marketplaces and app payments open new avenues for malware, fraud and scams, and privacy and security risks.

Of course they disagree with Japan’s MSCA on some of these things. If Apple didn’t disagree, they’d implement these features worldwide, not make them specific to Japan. And since they’re not applying these compliance measures worldwide, it’s correct for Apple to explain why.

But on the whole, this is a gentlemen’s disagreement — a polite agreement to disagree, with Apple making their case but then implementing the necessary measures for compliance without complaint. A polite explanation that they see some of these measures as introducing privacy and security risks is not a complaint per se.

This is of a piece with Apple’s longstanding respect for and relationship with the Japanese government. Back in 2021, Apple changed the rules for “reader” apps in Japan to allow linking to websites, in order to comply with a ruling from the Japan Fair Trade Commission (JFTC). In Apple’s announcement, App Store chief Phil Schiller said the following:

“Trust on the App Store is everything to us. The focus of the App Store is always to create a safe and secure experience for users, while helping them find and use great apps on the devices they love,” said Phil Schiller, Apple Fellow who oversees the App Store. “We have great respect for the Japan Fair Trade Commission and appreciate the work we’ve done together, which will help developers of reader apps make it easier for users to set up and manage their apps and services, while protecting their privacy and maintaining their trust.”

You can search, but you won’t find quotes from Schiller, nor any other Apple representatives, speaking of their “great respect for” and appreciation of the work they’ve done together regarding the European Commission and the DMA. Chance Miller, in his above-linked report at 9to5Mac, wrote, “Apple says Japan’s MSCA does a better job of balancing openness with security and user protection than the DMA in the EU.” I was in the same briefing with Apple representatives as Miller, and I’d say Apple was more clear than that. In addition to seeing the MSCA as more aligned with Apple’s own priorities regarding privacy and security than the DMA, Apple repeatedly emphasized that the MSCA respected Apple’s intellectual property in ways that the DMA does not. Complying with the DMA is adversarial and obtuse. An Apple spokesperson confirmed that, in contrast with the DMA, the guidelines that accompany the MSCA provide more clarity on things like privacy, security, safety, and youth protection. (E.g. apps distributed outside the App Store in Japan still require age ratings. There’s no such requirement in the EU.)

Because of the DMA, Apple has delayed and outright withheld major features in the EU. iPhone Mirroring, one of Apple’s best new features in recent years, is still unavailable in the EU. Apple fully expects more features to be delayed or withheld from the EU as time goes on. (With Apple Watch, they’ve now been forced to remove a feature that existed since Apple Watch debuted in 2015.) There have been no such feature delays (let alone withholdings) in Japan, nor does Apple expect there to be. The MSCA targets specific issues related to competition: how iOS apps are distributed, and how they are monetized. The MSCA choice-screen mandates for web browsers and search engines are clear, and don’t impose any odious or particularly confusing obstacles to users.1 Apple has made clear that they don’t agree with every aspect of the MSCA, but if you read between the lines, you can see a begrudging acknowledgement from Apple that the MSCA is well-intended, clear, and attempts to strike a balance between user experience, privacy, and security; respect for Apple’s intellectual property; and the anticompetitive aspects of Apple’s control over app distribution and payments that the law was written to address.

There is a mutual respect here between Apple and Japan that is completely absent between Apple and the European Commission. The MSCA, through its focus and clarity, is also more respectful of users. Users in Japan get the benefit of alternative app distribution (AltSTore is already there) and alternative payment options with no trade-offs like delayed or withheld features. It’s hard to find anything aside from small nits to complain about in the MSCA. It arguably gives Japanese users a better, more robust iOS experience than what Apple offers to the rest of the world.2 The DMA, in contrast, has given EU users a worse iOS experience.

It’s the practical results of legislation and regulation that matter, not the intentions. The Japanese government seemingly gets that, and acts accordingly.


  1. I think these mandatory choice screens are rather stupid. They have not proven to be effective in Europe. They’re a feel-good mandate for bureaucrats. Look, here’s a whole screen that we have forced upon every single user — visible proof that we have done something. Who cares whether most people do not know what a “default browser” is, or what a “search engine” is? We’ll make them pick anyway. The end result is that nothing has changed in terms of browser or search engine market share. All they’ve really accomplished is to make first-run onboarding time slightly longer. But — so long as users aren’t forced to face these choice screens repeatedly, they’re only a minor irritation. They’re like a mandatory “you should wear a helmet” warning label on a skateboard. You peel it off and throw it away, and the percentage of skateboarders who wear a helmet remains unchanged. ↩︎

  2. If we had alternative iOS app marketplaces in the US, like they do in the EU and now have in Japan, ICEBlock might still be available for download. I say might because it’s impossible to know whether Apple would attempt to stymie ICEBlock at the notarization level, given some of the cases where they’ve used notarization to block apps in the EU↩︎︎

Can we make America feel more affordable?

Americans are upset about the economy. And what are they upset about? Affordability. On polls about America’s most important problem, the cost of living consistently comes in ahead of other issues like inequality, deficits, wages, and unemployment. Here’s the latest from Echelon Insights:

Trump’s approval rating on inflation is lower than for most other issues:

Source: Nate Silver

If you’re an economist, this might strike you as a bit odd, because inflation itself is still fairly low, and around 2.7%:

Alternative measures are even lower.

And real wages — i.e., how much an hour of work can buy for the average worker1 — are rising strongly again, after falling in 2021-22:

Of course, lots of regular people don’t trust official statistics. But regardless of whether they rely on government numbers, people’s own inflation expectations are falling, and yet the percent of Americans who blame high prices for their poor personal finances is still near record highs:

Note that for decades, these two numbers tracked each other very well. But in the years since the pandemic, anger at the cost of living has become unmoored from how much people think the cost of living is actually rising.

That’s strange, right?

America and the World

I wasn’t able to do a fresh interview this week, so here’s a link to a talk I had with Martin Wolf for the FT. Transcript below.

TRANSCRIPT

Wolf: Paul, good to see you and talk to you again.

Krugman Good to see you, too, Martin.

Wolf So according to a new National Security Strategy document released by the White House last week, I appear to be living on a continent that faces civilisational erasure. I must say, it doesn’t feel like that.

Krugman Yeah, the same document says that we’re going to help Europe correct its current trajectory by helping, among other things, patriotic parties, which I think basically means parties like Germany’s AfD.

Wolf So Paul, there really is only one place to start, and that’s with America’s new National Security Strategy. So let’s go over its main points and what you make of them. Let’s start with something pretty fundamental.Does the absence of a liberal values mission in the NSS indicate the end of US exceptionalism, or at least US moral endeavours in the world, as a foreign policy principle? Is this all gone?

Krugman Oh, it’s more than gone. I mean, this document goes beyond dropping the historic US commitment to liberal values, democracy, whatever you want to think of as being the distinctive, exceptional American contribution to the world to sort of actively opposing it. I mean, quite a lot of the document is meandering boilerplate.

Some of it reads as if it was translated from the North Korean, with effusive praise for Dear Leader. But it is crystal clear on Europe, which it basically says, Europe better stop adhering to these liberal values, better stop admitting people from other places, or else.

Wolf So John Fitzgerald Kennedy’s famous ‘Ich bin ein Berliner’ at the Berlin Wall is now absolutely ancient history?

Krugman Oh, very much, and even Ronald Reagan, not one of my favourite presidents. But Reagan said: ‘We are a shining city upon a hill.’ And that’s definitely not the message that we’re getting from this document.

Wolf Now, one question before we get to this body blow to Europe, which I certainly am interested in and want to focus on, but I am quite intrigued by how this administration frames its competition with China. It clearly acknowledges the rivalry in tech, the economy, and military matters. But it doesn’t stress any sort of ideological competition.

It’s really just a set of interests. And it also implies in other places that its main focus is regional, that what the US wants to be is the dominant power in its regional sphere of influence, which is the Americas. It sounds as though, in addition to getting away from ideological competition of any kind with China, it’s sort of quite willing to hand over the rest of the world, which is pretty well all the world, economically speaking, outside the US - let’s be clear about that - to China. This is really a very weird way of framing an interest-based policy, isn’t it?

Krugman Yeah. I mean, Maga, make America great again, was a very protean slogan. It could mean whatever you wanted it to mean. But one of the meanings was clearly

that we were going to stand up against China. Trump released a national security statement during his first term that put rivalry with China at the core, although the actual policies proposed were disastrous. But that’s almost disappeared from this document. We’re really not going to try and do anything, at least this doesn’t say anything, about significantly contesting China’s technological progress, Chinese influence in the world outside the western hemisphere. We’re much more concerned with making sure that there aren’t too many non-white people living in Europe than we are with great power competition with China.

Krugman I mean, with the exception that, of course, at that time, the US wasn’t at all interested in Europe except to keep it out of the continent, it reads sort of rather early 19th century as a perspective upon the world. And I’m really surprised by this because it’s only really emerged during this administration, this second Trump administration.

Wolf Just briefly, what is driving that? Where is it coming from?

Krugman First of all, I’m not sure that there’s very much genuine interest in the western hemisphere. I mean, I don’t think - it is true that we have actual - we’re putting a lot of US taxpayers’ money on the line in an attempt to bail out the president of Argentina. And we put a lot of diplomatic capital on the line trying to punish Brazil for having the temerity to put a former president who tried a coup on trial. In terms of actual influence, I mean, it’s not clear that there’s much there going on except that the western hemisphere is a place to do things that this administration wants to do, like bomb small boats and then kill the survivors. So you sound like a crazy person whenever you talk about this administration’s policies, but that’s the reality. So I very much doubt that they have a coherent strategy that says we’re going to try to establish a Monroe-style sphere of influence. I think it’s more that, for various reasons, focusing on Latin America is convenient for them right now. So I think we should come back to that when we consider China and the broader competition for influence, which is clearly there.

Wolf There’s no doubt about that. But let’s first go a little bit deeper into what all this means for Europe. When we last spoke, you were rather optimistic on Europe.

So explain why you were. And has this really changed that perspective? Because I must say that, in Europe now, I sense in my discussions asked, people are really pretty shocked because to them it seems that the Americans have come out, essentially, and said, we are your number one enemy, pretty well. We absolutely despise your political arrangements. We want to replace your governments with governments like ours, of the far right. And well, for Europeans, that starts reminding them of the ‘30s. So this is really pretty terrifying. So where do you think it leaves Europe?

Krugman The United States has much less power over Europe than it imagines it does. European exports to the United States are under 3 per cent of European GDP. It’s not that the European economy is dependent upon access to US markets. It’s not even as dependent, I think, as many people think, on US technology. It has been dependent upon US national security guarantees. But that’s a choice. Europe’s GDP is not very far short of America’s. Europe certainly has the resources to be self-sufficient. So in a way, this may all serve as a wake-up call, saying, hey, Europe, you’re on your own. It’s time to actually recognise your own strengths. And I still, I mean, if we get there, I’m actually doing a bit more sort of background work. And I’m even more sceptical of the Europe in decline narrative than I was a few weeks ago. People should have seen this coming in Europe.

Wolf But it is still kind of shocking to see it out there in black and white.

Krugman Well, they have learnt, haven’t they? I’ve referred to this as learned helplessness.

Wolf After the war, people felt - the Second World War - people, obviously, were very grateful for American vital assistance in winning the war and in, then, in creating and supporting the institutions of a new Europe, economic and political. And most Europeans, not all by any means, but most Europeans have felt pretty grateful for that.

They’ve also quite liked not having to make all these difficult decisions. Now, suddenly, as it were, autonomy has been thrust upon them, to misquote Shakespeare. Obviously, they can. The resources are clearly there. But it could take a few years, and these could be very, very bumpy years.

Krugman Well, yes, but I mean, what are we talking about here, really?

I mean, the United States has complained that Europe does not spend enough on defence. Maybe we change that now that we think that Europe is the enemy.

But Europe spends a little under 2 per cent of its GDP on defence. The United States around 4 per cent. 2 per cent of GDP is not a huge... extra 2 per cent is not a huge burden. And it would take, actually, considerably less than that for Russia, as a rival to Europe, to be a joke because Europe remains immensely wealthy. So the resources are there.

Wolf The political cohesion has been really problematic. And it’s still... the European Union is still very much subject to being hamstrung by various kinds of blocking coalitions, although the US government is looking less and less able to get things done, as well.

Krugman I don’t think it takes as long as people think. I mean, one of those sort of random facts: who is the world’s largest producer of artillery shells right now? The answer is Rheinmetall, in Germany. Europe has reacted quickly in some aspects of just plain raw military clout, already moved into a surprisingly strong position.

Wolf So in terms of economic policy, talk about wider issues. If we were going to talk about accelerating the move towards strategic autonomy, economically, what would Europe have to do? Obviously, they’d have to spend somewhat more on defence,

I agree, something like a couple of percentage points of GDP. It would have to be... they’d have to get rid of a lot of the duplication which they now have, so take advantage of scale. That’s quite a big issue. But they did this famously in civil aviation, where Airbus has been a tremendous success, obviously. So they’re used to doing things like that. They’re going to have to mobilise more manpower. But I mean, the EU alone, leaving aside UK, has, I think, at least 3 to 4 times as many people as... I think it’s about 4 times as many people as Russia. So that should be manageable. And Europe is the largest world trader in aggregate, I think, still. And so it will remain capable of forming worthwhile trade agreements with the rest of the world. And I suspect the rest of the world - and I’ve made this point before in other contexts - will want to minimise its complete dependence on just the US or China. And most of the countries in the rest of the world have a degree of freedom. So they’re going to continue to want European markets and good relations with Europe because a third pole is desirable. Taken together, this doesn’t look too bad, does it?

Krugman No, there’s a widespread perception that Europe has fallen very behind technologically, which is not exactly wrong but, I think, in many ways, misleading. Europe definitely has a much smaller footprint in information industries than the United States does. All of the big companies in that area are US or Chinese. Quite a lot of the stuff... I mean, AI is being undertaken largely in the United States and, in a different version, in China. So those are important things. And there’s a really strong case for some kind of European industrial policy, if only to enhance autonomy.

Wolf Overall, the numbers say that European productivity has lagged well behind the United States since about the year 2000.Yes. And I’m actually sceptical. I’m not sure that those numbers mean what they appear to mean. And that’s a whole... that’s a way too technical discussion to have here now. But I’ve been doing some calculations on real wages. European real wages have grown about the same rate as US real wages.

It’s not as if the ordinary experience of the economy has been bad for Europeans. And if we look at the application of modern technology in daily life, that’s every bit as obvious in Europe today as it is in the United States. So it’s not clear to me that Europe has... it’s like there’s a segment that Europe has fallen behind in.That’s a solvable problem, if Europe has the will. If you really use the resources available, there’s no doubt about it.

Wolf Maybe we should take a bit of a leaf out of the book of the Biden administration’s effort with targeted industrial policy, which this administration has completely scrapped. It looks at a great deal more sensible than what they’re now following, scattergun, unpredictable tariffs.

Krugman Yeah. We were talking about how the Trump administration has downplayed, all of a sudden, rivalry with China, seems to have dropped off the agenda and not just in the National Security document, in terms of actual policy, as well. Europe has a real - I mean, I don’t exactly what the grounds for action - I think it’s much less legalistic and much more than it is the United States. But we have Section 232 tariffs, which were designed to give a lot of flexibility in dealing with national security interests. And Europe clearly needs something like a Section 232, where the national security threats are coming as much from the United States as they are from China.

Wolf But we would almost inevitably end up with conflict with both because we want to... people will want to preserve vital industries in this world, in Europe. I accept that the basic fundamental technologies have to be available in Europe. That means we have a concern with the US now, and we obviously have a concern with China. We’ve just heard that the trade surplus of China has been $1tn. There have to be counterparties to that. And if the US doesn’t want to be the counterparty, it looks as though it will be Europe.

And it’s pretty obvious the Europeans are not going to have that.

Krugman Yeah, you can be as much of a free trader as one can be in good conscience and yet having $1tn trade surplus all head to China because the United States has gone protectionist. The dislocation, in some sense the GDP welfare calculations, whatever, are irrelevant. You cannot accept that level of disruption. And I think, actually, there are macroeconomic consequences.

Wolf There are macroeconomic implications. I think we discussed this, as it were, in our different writings 20 years ago in the early stage of the huge expansion of the Chinese surplus and the consequences for macroeconomic policy. So China has to change. And Europe has to adapt. But the US is really something of a threat to Europe. So let’s consider just briefly the political sideof that threat. This seems to be an idea that European states have to facilitate, essentially, the rise of what the US refers to as patriotic parties, essentially, far right parties. And a key emphasis, very clearly in this document, when it refers to the civilisational crisis of Europe, it’s very clearly framed as racial.

Krugman Yeah. It’s absolutely astonishing to me. I suppose I’m naive that it’s got so far that the US considers the civilisation it’s defending not as a series of values, but as just about - let’s be brutal - skin colour and religion. What does Europe do when confronting a power that has the aim of causing racial war in your continent and putting in power parties with - again, be brutal – which are at least ideologically rather similar to well, we have no other way of putting it, the Nazis.

Wolf That’s the echo we all hear when they say, we must go back to defending our civilisation. That inevitably sounds Nazi. How do you deal with this?

Krugman Well, I think you deal with it by saying, no, hell no, expressing outrage. I’m not sure exactly how it plays in European politics. But in a number of other countries, including Canada, which is far more dependent on the United States than, just because of geography, than Europe is, Trump has been a highly effective campaigner on behalf of liberal values, also the Liberal party.

Wolf I agree. Mark Carney is prime minister of Canada in an election that was supposed to be a devastating defeat for his party, largely because Trump so visibly was on the side of his opponent, and that turned the vote. It’s at least possible...

Krugman I mean, something like that, to some degree, happened in Brazil, as well. So in some ways, the famous phrase from Franklin Roosevelt in 1936 about his enemies, ‘”I welcome their hatred,’ I’d like to see. I think it’s probably a good idea for European politicians to say we welcome Trump’s hatred. If there’s something he wants, this is something Europe should not want. I think, actually, it is possible - and the next few years are going to tell us - that exactly what you described will happen.

Wolf If it continues in this way, with this sort of rhetoric and - I’ll come to another aspect of it - of action, then I think the hostility to anybody who clearly puts himself or herself forward, as it were, as Trump’s avatar in Europe is going to be very substantial. It’s going to be really a huge, crucial moment in European history. And this other aspect is the role of big tech. I mean, this is quite extraordinary, to me, that essentially they are making foreign policy. 10 years ago, 15 years ago, I thought of big tech as predominantly liberal. Well, that’s certainly gone. And they’re basically claiming that they are entitled to complete free rein. There should be no controls whatsoever on what they produce because free speech. And they seem to be utterly in control of US foreign policy. That’s really quite extraordinary. Is that going to continue? Should we reckon that just a feature, not a bug, in US foreign policy now?

Krugman Well, what we do need to say is that it’s very much a partisan thing. Big tech used to have... to some extent probably still does, but used to have a lot of power in both parties. It was a lot of the tech guys were major contributors to Democrats. They have very much tied themselves now to Trump’s waggon, and the attempt to use US government power on their behalf. I mean, the part of the conflict, aside from the, how dare you allow non-white people into your countries, but part of the conflict is, how dare you try to have some prudential regulation of social media... Indeed. ...digital services in Europe. And the people who are gone crazy about that, Elon Musk calling European bureaucrats ‘woke Stasi commissars,’ I think...

Wolf That’s right. ...they have very much identified themselves now with Maga, with Trump.

Krugman And if the United States is able to turn this around, if we are able to shake off this malign movement, then US foreign policy will also change. So this is not... hopefully, it’s not a permanent feature of US-EU relations. But you should behave as if it might be a permanent feature. And it’s wild. I mean, we have our commerce secretary threatening to keep steel tariffs high on Europe if Europe doesn’t stop attempting to prevent the psychological and social harm caused by untrammelled social media.

That’s amazing. The tech bros want the US government to act on their behalf in Europe the way that United Fruit Company used to expect the US government to do its bidding in the banana republics of Central America, which is... that’s where the banana republic name comes from.

Wolf The other policy that Europe follows that they want to savage is anything to do with climate change. Now, this is, of course, seen increasingly by the world as, essentially, a war of the US on the world because most people recognise the importance of doing something about this.

Krugman The worst part is not simply that Europe is encouraging wind and solar power, but that it’s working - not great. Prices are a little high. There are some questions. But when you have Britain relying very, very heavily now on wind power, some of the European continental economies relying very heavily on solar power, the demonstration

that you can actually do this is something that really, really annoys the American right as much as anything else. If Europe is going to, were to say, OK, never mind the wind and the sun, we’re going to go back to fossil fuels, where are those fossil fuels going to come from? And the biggest answer is actually natural gas from the United States. So just on national security grounds, Europe should be pushing for renewable energy. I mean, they were getting gas from Russia, and that has turned out to be a really bad idea. Being dependent on liquefied natural gas from the United States is almost equally bad as an idea.

Wolf Yes, and one of the attractive aspects of clean tech is that even Donald Trump can’t stop the sun shining or the wind blowing. He’ll try, but yeah. I think that’s still beyond him. So it’s time for a short break. And when we come back we’ll be talking about the battle for supremacy between the US and China, particularly economic supremacy, and whether China has already won.

Wolf So let’s talk about China and the US. You’ve argued that China isn’t the world’s number two economybut is, in fact, already the world’s number one economy. Can you explain that view?

Krugman In terms of the dollar value of GDP, China is still number two. But the overall price level is lower in China, which is a well-known thing. China is still, per capita, it’s a middle income country, not a high-income country. And there’s a well-established relationship, the Balassa-Samuelson effect, which people do not want to know about. But it is, in fact, pretty much uniformly the case that countries at a middling stage of development tend to have cheaper non-traded services than countries with a more advanced level. And therefore, the true volume of stuff they produce, the real quantity of goods and services they produce is larger than you might infer from just looking at the dollar value of their GDP. And China, on a purchasing power basis, the economy is already substantially larger than the economy of the United States. The United States is still ahead in cutting-edge technologies, although that’s a surprisingly fragile lead.

And the Chinese have shown an awesome ability to catch up technologically, or at least catch up most of the way technologically, in areas that they consider a priority. So I think there’s really no serious question that, at this point, China has the bigger economy. For investors, it’s not as big a market,because the dollar value of its GDP is smaller. But we’re really not close. And everything that’s happening on the ground in terms of support for science and technology, in terms of having any kind of coherent industrial strategy, says that the gap between China and the United States is going to get wider.

Wolf One of the factors, obviously, is the rate at which countries invest. We know that quite a bit of Chinese investment is inefficient. But quantity is quality, to some degree. And if you look at China’s annual dollar savings, it’s even bigger in GAAP and PPP terms, they’re actually as big as US and Europe together. Even if you assume that a lot of that is wasted... and quite a lot of that is wasted in buying really pretty poor assets because of this huge trade surplus of theirs. But nonetheless, their capacity to mobilise resources in pretty well any sector they’re interested in, as they’ve shown with clean tech, is pretty daunting. And the US has got nothing to compete with that because they just aren’t these flows of savings or investment.

Krugman Yeah. There’s been nothing like the situation of China before. In the past, the world’s biggest economies have also been its richest per capita. And this is, for the first time, that the biggest economy is, in fact, not also at the top in terms of per-capita GDP.

And in some ways, you might think that leaves China with some areas that it just really can’t compete with the United States, except that that’s probably not true, because although China’s overall technological level kind of lags still, China is so big, has so much deployable investment, so many deployable savings, and an ability to focus on...

I mean, industrial policy can sometimes go very badly wrong. But if there’s a sector that the Chinese think is really important for them to dominate the world in, they pretty much can do that. And the United States has no ability to counter, at least certainly has no desire to counter that in any systematic way now. So sure, this is a world where, yeah, the United States is still richer, our standard of living is still higher. But in terms of any kind of geopolitical competition, there’s almost nothing. If it goes head to head between the US and China, my money would be all on China.

Wolf So if you look at this, imagine you were sitting in Beijing, and you were looking at the way America has behaved since Trump was inaugurated, look at the trade war, look at what they’re doing in domestic policy, particularly, as you said, science and technology. Now, this National Security Strategy comes along with its very strange ideas about spheres of influence and no real indication of a desire to challenge China, as far as one can see. Would you conclude, well, basically, it’s all done? We are going to be the top power. We are going to be a more reliable trading partner for most countries in the world, including even Europe. I mean, the Europeans are very worried about this industrial competition, all the rest of it. But China hasn’t been behaving in quite the way the US has been behaving. Look at the way it’s been behaving with Brazil or India. So the Chinese sort of feel, if you look at all these things together, their scale, their mobilisable resources, the international relations that the US is now busy sacrificing, including its most important allies, which, as you’ve pointed out, are the basis of the larger bloc it had around it - and I wrote about that very recently when I talked about a world global economic fragmentation - the Chinese must just feel that everything is falling into their lap.

Krugman Yeah, I mean, I don’t know whether the Chinese, whether Chinese officials, what they do when they’re feeling triumphant, whether they rub their hands with glee or they giggle or what. Whatever it is they do, they must be doing it because, my god. It’s funny. I was just... kind of random, I was reading some posts on history on Substack and someone who was amazed to discover that the Roman Empire, how did Rome conquer the world? And yeah, the Romans had good armies and good soldiers, but not that much better than anybody else. Ancient Rome’s real strength was its ability to cultivate and assimilate allies. It was the strength at building alliances that made the Roman Empire. The United States used to be really good at that. We were the leader of the free world. And it’s still true, as I wrote in the piece that appeared just before we had this conversation, that the former free world, collectively, is still a much bigger economic power than China. But the United States has just declared that large parts of what we used to call the free world are actually our enemies. And we are, on our own, without allies, are not a match for China. So the Chinese must be feeling, hey, the second Cold war is over, and we won.

Wolf I mean, indeed, in the book I wrote, The Crisis of Democratic Capitalism, quite a lot of columns were basically, over the years, the recent years, were framed around the idea China on its own is so big and has such huge potential that a country with a quarter of its population - that’s roughly the relationship between the US and China - is very unlikely to be able to match it on its own over the next 30, 40, 50 years.

Nothing’s certain. But if you look at the difference, do you really think China can’t get to real GDP per head of half of US levels? When you just do the arithmetic, you can see where you end up. But actually, the US had this vast alliance and lots of friends and lots of countries which at least leant towards it. India is obviously an incredibly important example because of its scale. And it’s just burnt them all. And what’s astonishing to me is there doesn’t seem to be any serious debate about the implications of that. I may be wrong, but among the foreign policy community, what I’m seeing is nothing but complacency. There are distinguished exceptions. Obviously, there’s huge concern in the US about the domestic side. That I understand fully, this attempt to create a despotism. But I’m really astonished at how few people have been arguing that the US is just burning all its major assets in this competition. Maybe the explanation is, ultimately, these people don’t care about the competition with China. They just care about the societies they create at home. Well, that’s probably true of... it’s not probably, it’s definitely true of the Trumpists. This whole competition with China, great power, that was always an excuse. It was always a reason to do what they wanted to do domestically. And if they’re given a choice, I mean, I was wondering how much pushback I’d get, but I just said that Trump has, effectively, chosen white supremacy over national greatness. And that’s clear. Given that choice, that’s the choice they will make.

Krugman In many ways, this has been prefigured. This explicit downgrading of international competition and in the National Security Strategy is prefigured by everything else that’s been going on. Let’s not forget that all of Trump’s tariffs are flat violations of past agreements US tariffs were not set... Of course. ...in isolation. They were set through global negotiations. We promised Europe. We promised Canada. We promised the world a lot. And then Trump not only just ripped all of that up, but did so without even explaining why. No sense that US promises are something that should be honoured or, if you’re not going to honour them, you owe the world an explanation. So what authority - diplomatic, moral, however you want to measure it, what authority do we have in this world now?

Wolf Well, of course, the excuse they gave - but they’ve never justified it with anything rigorous, of course - is that the rest of the world was ripping us off. And Europe, of course, was presented as being the arch ripper-offer, if I may use that phrase. And that is obviously part of what justifies the view, which seems to be very clear now, that Europe, which always has considered itself sharing values with the US, and objectives and aims, is actually the enemy, this very, very strong sense of grievance. So the white nationalism is clearly important. But the other point, at least with Donald Trump himself - I don’t know with the others - is this very profound sense of this incredibly powerful and, on the whole, successful country, that it’s been ripped off. Again, that’s a psychological problem, isn’t it? I mean, it’s nothing... you can’t really interpret that, coming from this country of all countries, as a sort of credible position.

Krugman Yeah, especially... even if you buy the bad economics of Trumpism, the belief that bilateral trade imbalances mean that you’re being ripped off by the other guy, that they sell more to you than you sell to them, that that means that somehow or other that you’re subsidising their economy... it makes no sense, but that is what Trump has often said. But the European Union, if you include exports of services as well as goods, EU-US trade is almost balanced. We don’t even actually have a big... Absolutely. ...trade deficit with Europe. So even on Trumpian economics, it makes no sense at all. But the facts have a well-known liberal bias, I guess, or something. It is, I think, ultimately, the sense of being ripped off here comes more from we don’t like the fact that the Europeans still have the values that we used to have. And then we’re going to make up some other story to justify our hostility.

Wolf Now, in this world that we’re envisaging- I think we’ve considered this before, but I’ve thought about it some more - if you were a rational ruler of a Latin American country, of a south or east Asian country, which isn’t itself a superpower yet, as it were, how would you navigate this? Presumably, you don’t really want to choose China. There are problems there. You want to manage and contain your risks vis a vis the US. You probably don’t want to close your economy up. It seems to me part of what you would want to do is to get really quite close to Europe. But how do you think this will play out? And a particular issue there, since we started with this, is this whole Monroe Doctrine revived attitude of the US, the sphere of influence. Most of the - not all - Mexico is obviously an exception, but many of the south American countries, because their commodity exports, their biggest market is China. America is a competitor, not a natural market. They’re not going to want to... they’re going to want to continue to trade with Europe and China. Is the US somehow proposing to blockade them? Are they envisaging that somehow the south American countries will be invaded or, in some other way, forced? I mean, I feel the same about Canada. Where’s the beef here? What is actually underneath all this insane rhetoric?What, in concrete terms, might it mean for US policy in the rest of the world? What choices might we be faced with?

Krugman Yeah, I mean, the idea of certainly of south America as a US sphere of influence, I mean, even on just raw geography, Brazil is as close to Europe as it is to the United States. Exactly, of course. Argentina is, and in economic terms, they’re roughly equidistant in some kind of economic distance, from the US, China, and Europe. And in many cases, they do more trade with China and Europe than they do with the United States.

Wolf Indeed they do.

Krugman And if you ask the question, why single out Latin America, I get a maximum cynicism. I mean, we can go out there and sink small boats in the Caribbean. I don’t think we could get away with doing the same thing in the Mediterranean. If you want to go out there and kill people, Latin Americans are kind of the targets of opportunity, regardless of whether there’s any real motivation for it. I’m sorry, that’s... again, it’s hard to talk about this stuff without sounding crazy, but that’s just kind of where we are. But I don’t think there’s a coherent doctrine. I think if you look for a coherent geopolitical doctrine in that National Security Strategy, you won’t find it. I actually read it quite carefully and was very sorry. Page after page of meandering, circular drivel, coupled with occasional sycophantic praise for the president until you get to the European section. The only thing that is really coherent is, we hate Europe. And the rest does talk about, yes, well, western hemisphere is ours. We tried invading a country to produce regime change back 20 years ago, and it did not go well. And I can’t imagine... no, I can’t imagine all kinds of things, but I would be really surprised if they’re willing to actually apply serious force towards regime change in South America. I would have thought that regime change in a vast continent like that... the one thing I thought about the Maga movement is they really didn’t like foreign wars.

Wolf Well, that would be beyond insane. I mean, the conclusion I’m reaching from this discussion, essentially, from the European perspective, is something like this. We seem to have a superpower that we trusted, respected, and in many ways profoundly admired. It has become, more or less across the board, economic policy, domestic policy, foreign policy, sort of, at best, senile. But it has one coherent idea. It hates us... Yeah. ...that is to say, Europeans, because we’re the last major liberal democracies left in the world. So my reaction to this is that it’s a combination of pity and fear, as it were. But the pity is not just for America. It’s also for all its former friends. Can you give us one ray of hope that this will, before we go, that this will not last, that this sort of doctrine that we are now seeing emerging at home and abroad, all that we’ve experienced this year and this paper, that this will be a temporary phenomenon, and we will get back something like the US we knew and loved?

Krugman Well if there’s a ray of hope, it would be how Latinos voted in the New Jersey election last month... I mean, kind of seriously. Trump’s ascent to a second term in the White House does not now look like it was a fundamental structural change in US politics. It was a lot of relatively low-information US voters who actually believed that Trump could bring down prices and have been very rapidly disillusioned. So assuming that the attack on democracy at home hasn’t gone too far, it’s very, very likely that Maga will at least be set back seriously politically in the midterm elections. 2028 is a long ways away, but the possibility... I would say there’s better than even odds that we do not have this kind of regime in the United States a few years from now. Now, that’s not the same thing as saying that America will be back. I mean, it’s going to be... I don’t expect in my lifetime to see us repair the damage to our reputation, to our credibility that we’ve just done. But meanwhile, Europe needs to put on its big boy pants, or whatever is the appropriate metaphor these days, and say, hey, we are a superpower, too. And we may not be quite as big an economy as America, but on the other hand, we have a lot of strengths that America is throwing away. So time for us to take charge of our own destiny.

Wolf I very much agree with that conclusion. It’s very much what I have been and will be arguing, and I hope that Europe does respond because the alternative is really pretty horrible. I think this has been a very illuminating discussion. And next week, we’re going to be answering your questions. We’ve had plenty of comments on YouTube and Spotify, as well as the FT website. So if you’ve got a question you want us to answer, do comment on this whenever you’re listening or watching. Or email us at economics.show@ft.com. And we’ll do our best to answer your questions.

Krugman The question and answer is always the most fun of any kind of presentation, so this should be the most interesting part.

Wolf So what’s your cultural coda this week, Paul?

Krugman OK. It is funny. I was searching for something and then discovered, as I often do, that I had already used it for the Substack, but I’ll bring it back. And for once, I’m going to do classical music. There was a magnificent performance of Beethoven’s Ode to Joy, held for a vast public square in Maastricht a few years ago, Andrew Rieu conducting. And there’s something about it. There are a lot of, YouTube first, lots of panning through the crowd. And there are people weeping, as they should be. Let’s try to remember all the great things that actual western civilisation, not the caricature of it that the Trumpists want, has done and reclaim and move it forward.

Wolf Well, that’s a wonderful coincidence because I was going to suggest exactly the same passage. But it occurred to me, if they can find it, if I remember correctly, that just after the fall of the Berlin Wall, Leonard Bernstein performed it, I think, in Berlin.

And they changed the word. The first word in the German is ‘freude,’ which is ‘joy.’

But I think he did a performance in which the first word was ‘freiheit,’ ‘freedom.’ And in a way... Oh, wow. ...that is even more appropriate to this moment because he was symbolising the freedom that the fall of the Berlin Wall meant, which was, to me, as I wrote at the time, the most exciting political event of my life, watching the division of Europe end. And this is the Europe that Trump and his minions wish to destroy and turn back into a fascist system. Because of course - another little point - that choral song, based on the Schiller poem, is the anthem of the European Union and therefore could not be more appropriate at this moment, when the European Union, which was such a magnificent idea of co-operation and peaceful relations in a continent that had been destroyed by war over the centuries, but particularly in the first half of the 20th century, this is so symbolically powerful, the connection with that, the connection with European history, one of its greatest geniuses, and of course, the hopes of contemporary Europe. You’re at the EU seeing up close, reading Commission documents, it’s easy to get annoyed at all of the pettifogging bureaucracy and all of that. But the reality is, given the past few centuries of European history, what a magnificent thing it is for Europe to have gotten to where it is today.The longest period of peace in European history since the fall of the Roman Empire.

Krugman Yep.Thank you, Martin.

MARTIN WOLF: Till next week.

Q&A With the Pilot, Volume 7

AN OLD-TIMEY QUESTIONS AND ANSWERS SESSION.

Eons ago, in 2002, a column called Ask the Pilot, hosted by yours truly, started running in the online magazine Salon, in which I fielded reader-submitted questions. It’s a good idea, I think, to touch back now and then on the format that got this venerable enterprise started. It’s Ask the Pilot classic, if you will.

Q: I was on a jet with five seats across: two on one side, three on the other. Does an asymmetrical configuration like this have any bearing on flight? What if all the seats on one side were full, and empty on the other side?

Lateral balance is wingtip to wingtip, not cabin wall to cabin wall. In other words, for purposes of this discussion, a 747 isn’t 20 feet wide, it’s 200 feet wide.

Imagine an airplane as a see-saw. The ends of the see-saw, where the kids are sitting, are the wingtips. The fulcrum, in the center, is the cabin. The leverage is coming from the distance between the wingtips and the fulcrum. Shifting weight from one or two inches left of the fulcrum, to one or two inches right of it, makes no measurable difference.

Longitudinal balance, front-to-back, is a bit more important, though still less than you’d think. Passengers will occasionally be asked to move forward, or rearward, depending on the situation, to help fine-tune the plane’s center of gravity. Cargo and fuel are usually part of this equation. Are you going to crash if people aren’t in the correct rows? Of course not, but technically the plane might be nearing its CG limits.

Passengers and their bags account for a surprisingly small portion of a plane’s overall weight. The jet I fly has a maximum takeoff weight of about 500,000 pounds. A full load of people and their bags weighs around 55,000 pounds, or a bit more than ten percent of the total. Where they’re sitting doesn’t make much difference.

Q: Coming in to land one day, we were just about on the pavement when suddenly we shot back up again. A few minutes later the pilot said, “The plane in front of us missed its turn-off and was still on the runway.” Which sounds terrifying… though I know from reading your site that sometimes pilots say things that sound scarier than they are.

True, and what you describe isn’t terribly uncommon.  Was it a “near miss”?  No. The go-around was initiated to prevent one. 

Runways at big airports usually have multiple turn-off points.  You take the one that is safest to take, based on your speed, regardless of which one the controllers want you to take. You might be planning for particular turn-off point, and/or ATC might ask you to minimize your time on the runway because of traffic following you, but it doesn’t always work out. You’re not going to force the turn and risk skidding or sliding or putting undue loads on the landing gear. If need be, you keep going and take the next exit.  If the plane behind you needs to go around, so be it.  

Q: As an international pilot, you obviously fly to many non-English speaking countries, which got me thinking about air traffic control protocols. Are communications with pilots conducted in English, or do American pilots have to be fluent in the native language of the places they fly to?

If so, I’d be fluent in about 20 languages. As it happens, English is the lingua franca of commercial aviation, and except perhaps for remote corners of China or Russia, all controllers and pilots are required to speak it.

But, depending on the country, they might also use their local language. In Brazil, for example, you’ll hear both English and Portuguese over the radio; controllers talk in English to foreign crews, but in Portuguese to local crews. France is another one. There are several.

I don’t like these multiple language airports because it’s harder to keep track of which planes are where. Pilots listen not only for their own instructions, but for those of other pilots as well. By creating a mental picture of what other aircraft are doing, they can orient themselves in the choreography of a crowded sky (or tarmac). This is more difficult when instructions and clearances are being given, and acknowledged, in a tongue you can’t understand.

Ask the Pilot Christmas, 2025

December 22, 2024

Welcome to the 2025 installment of “An Ask the Pilot Christmas.”

In years past I would start off with gift suggestions, but this time I don’t have any, save a tedious plug for my book. It’s in dire need of updating, but I suppose it makes a good stocking-stuffer.

You can expect chaos at the airports, as always. According to the International Air Transport Association (IATA), roughly 62 billion people are projected to fly between now and New Year’s Eve, 96 percent of them connecting through Atlanta.

In fact I don’t know how many people might fly. I haven’t been listening. In any case, it’s the same basic story every year: the trade groups put out their predictions, and much is made as to whether slightly more, or slightly fewer, people will fly than the previous year. Does the total really matter? All you need to know is that lines will be long and flights full. Any tips I might offer are simple common sense: leave early, and remember that TSA considers fruitcakes to be hazardous materials (no joke: the density of certain baked goods causes them to appear suspicious on the x-ray scanners).

For years I made a point of working over the holidays. When I was a bottom-feeder on my airline’s seniority list, it was an opportunity to score some of those higher-quality layovers that were normally out of reach. Other pilots wanted to be home with their kids or watching football, and so I was able to spend Christmas in Cairo, Edinburgh, Budapest, Paris.

That’s how it works at an airline: every month you put in your preferences: where you’d like to fly, which days you’d like to be off, which insufferable colleagues you hope to avoid, and so on. There are separate bids at each base, for each aircraft type and for each seat – i.e. captain and first officer. The award process then begins with the most senior pilot in the category and works its way down. The lowest-rung pilots have their pick of the scraps.

Festifying my hotel room. Accra, Ghana, 2014.

One of my favorite holiday memories dates back to Thanksgiving, 1993. I was captain of a Dash-8 turboprop flying from Boston to New Brunswick, Canada, and my first officer was the always cheerful and gregarious Kathy Martin. (Kathy, who also appears in my “Right Seat” essay, was one of at least three pilots I’ve met who’d been flight attendants at an earlier point in their careers.)

There were no meal services on our Dash-8s, but Kathy brought a cooler from home, jammed with food: huge turkey sandwiches, a whole blueberry pie and tubs of mashed potatoes. We assembled the plates and containers across the folded-down jumpseat. The pie we passed to the flight attendant, and she handed out slices to passengers.

Quite a contrast to Thanksgiving Day in 1999, when I was working a cargo flight to Brussels. It was custom on Thanksgiving to stock the galley with a special meal, and the three of us were hungry and looking forward to it. Trouble was, the caterers forgot to bring the food. By the time we noticed, we were only minutes from departure and they’d split for the day. I thought I might cry when I opened our little fridge and saw only a can of Diet Sprite and a matchbook-size packet of Tillamook cheese.

The best we could do was get one of the guys upstairs to drive out to McDonald’s. He came back with three big bags of burgers and fries, tossing them up to us just as they pulled the stairs away. Who eats fast food on Thanksgiving? Pilots in a pinch.

Fireworks explode only a few hundred feet from the ground, but when enough of them are going off at once, it’s quite the spectacle when seen from a jetliner. On New Year’s Eve, 2010, I was en route to Dakar, passing over the city of Bamako, Mali, in West Africa. At the stroke of midnight, the capital erupted in a storm of tiny explosions. The sky was set aglow by literally tens of thousands of small incendiaries — bluish-white flashes everywhere, like the pulsing sea of lights you see at concerts and sporting events. From high above, this huge celebration made Bamako look like a war zone.

Christmas Eve, Paris, 2017.

I’ve also spent a number of holidays traveling on vacation. Thanksgiving in Armenia, for instance. Another Thanksgiving in Timbuktu.

And with that in mind, here’s some advice…

Do not, ever, make the mistake that I once made and attempt to enjoy Christmas at a place in Ghana called Hans Cottage, a small hotel situated on a lagoon just outside the city of Cape Coast.

They love their Christmas music at the Hans Cottage, you see, and the compound is rigged end-to-end with speakers that blare it around the clock. And although you can count me among those people able to tolerate Christmas music (in moderation, and so long as it isn’t Sufjan Stevens) there is one blood-curdling exception. That exception is the song, “Little Drummer Boy,” which is, to me, the most cruelly awful piece of music ever written. (It was that way before Joan Jett or David Bowie got hold of it.)

It’s a traumatic enough song in any rendition. And at the Hans Cottage Botel they have chosen to make it the only — only! — song on their Christmastime tape loop. Over and over it plays, ceaselessly, day and night. It’s there at breakfast. It’s there again at dinner. It’s there at three in the morning, seeping through the space under your door. And every moment between. I’m not sure who the artist is, but it’s an especially treacly version with lots of high notes to set one’s skull ringing.

“Ba-ruppa-pum-pum,ruppa-pum-pum…” as I hear it today and forever, that stammering chorus is like the thump-thump of chopper blades in the wounded mind of a Vietnam vet who Can’t Forget What He Saw. There I am, pinned down at the hotel bar, jittery and covered in sweat, my nails clattering against a bottle of Star lager while the infernal Drummer Boy warbles into the buggy air.

“Barkeep!” I grab Kwame by the wrist. “For the love of god, man, can’t somebody make it stop?”

Kwame just smiles. “So lovely, yes.”

Building a Library of Science Fiction Film Criticism

Building a Library of Science Fiction Film Criticism

Back in the days when VCR tapes were how we watched movies at home, I took my youngest son over to the nearby Blockbuster to cruise for videos. He was a science fiction fan and tuned into both the Star Trek and Star Wars franchises, equally available at the store. But as he browsed, I was delighted to find a section of 1950s era SF movies. I hadn’t realized until then how many older films were now making it onto VCR, and here I found more than a few old friends.

Films of the black and white era have always been a passion for me, and not just science fiction movies. While the great dramas of the 1930s and 40s outshone 1950s SF films, the latter brought the elements of awe and wonder to the fore in ways that mysteries and domestic dramas could not. The experience was just of an entirely different order, and the excitement always lingered. Here in the store I was finding This Island Earth, The Conquest of Space, Earth vs. The Flying Saucers, Forbidden Planet, Rocketship X-M and The Day the Earth Stood Still. Not to mention Invasion of the Body Snatchers.

Note that I’ve linked to some of these but not others. Read on.

Image: Dr. Carrington and his fellow scientists of Polar Expedition 6 studying how the Thing reproduces in the greenhouse of an Arctic research station in 1951’s The Thing from Another World.

Naturally, I loaded up on the SF classics even as my son turned his nose up at this ancient material, with its wonky special effects and wooden dialogue. I never did make him a fan of older movies (not even after introducing him to the Quatermass films!), but just after I began publishing Centauri Dreams, I ran into an SF movie fan who far eclipsed my own knowledge of the genre. Larry Klaes was about the first person who started sending me regular comments on the articles here. That was just after I turned the comments section on in 2005. In the years since he has become a friend, an editorial confidant and a regular contributor.

Klaes on Film

Larry has been an author for most of his life, and he has demonstrated that for the past two decades with his extensive work for Centauri Dreams. His essays have ranged through astronomy, space science, and the history of humanity’s exploration of the heavens. Equally to our purposes, Larry has also had a life-lomg fascination with science fiction, which helped to spur his interest in space and related subjects from an early age.

You’ll notice that a number of the movies I mentioned above are linked to Larry’s articles on them. The ones without links are obvious targets for future essays. A look through the archives will demonstrate that Larry has tackled everything from 1951’s classic The Thing from Another World to Star Trek: The Motion Picture. He’s written in-depth analyses (and I do mean in-depth) on more recent titles like Interstellar and 2010: The Year We Make Contact. I disagreed with him completely on Interstellar, and disagreements are what make film criticism so much fun.

Moreover, Larry is the kind of film enthusiast who isn’t content simply to put forth his opinions. He digs into the research in such a way that he invariably finds things I had never heard of. He finds clips that illustrate his points and original screenplays that clarify directorial intent. He finds connections that most of us miss (see his treatment of 1955’s Conquest of Space in relation to the Swedish film Aniara and the genre he labels ‘Angst SF’). His coverage of Avatar was so comprehensive that I began talking to him about turning his essays into a book, a project that I look forward to participating in.

Larry’s latest is a deep dive into Aniara, little known in the US, with its depiction of off-world migration and a voyage gone terribly wrong. The film possesses a thematic richness that Larry fully explores as the passengers and crew adapt to dire circumstances with the help of immersive virtual reality. When I read this, I decided it was time to give Larry space in a separate section, as the blog format is too constricted for long-form work. Have a look at the top of the home page and you’ll now see the tab Klaes on Film. The Aniara piece is there, inset into a redesigned workspace that offers ready navigation through the text.

Image: I loved the film but Larry’s look at Interstellar makes incsize points about film-making, public perception and the development of the interstellar idea.

All of Larry’s film essays are now available in the new section, but thus far only the current one on Aniara is embedded in the new format. I’ll be seeing to it that all of the essays are reformatted going forward, so that the disadvantages of the blog format for longer writing are eased.

The goal is to create a space for film criticism that acknowledges the hold the SF genre has acquired over the general public, in many cases inspiring career choices and adjusting how the average person views the interstellar challenge. This is a long-term project, but my web developer Ryan Given at StudioRTP is brilliant at customizing the site’s code and he knows where we’re going from here. I couldn’t keep this site going without Ryan’s expert guidance.

As my own passions in film are by today’s standards archaic (I’m still a black and white guy at heart), I’m glad to have someone who can tackle not just the classics of the field but also the latest blockbusters and the quirky outliers. And I wouldn’t mind seeing Larry’s thoughts on the TV version of Asimov’s Foundation either. Let’s keep him busy.

The market for used underwear, in the journal Genre, sexualité & société

 The study of repugnant transactions and controversial markets can lead to some strange markets.

 In the latest issue of the journal Genre, sexualité & société (after right clicking to translate to English) :

Product qualification in a contested market: The case of the used underwear market
by Ludine Cayla and Julien Gradoz
https://doi-org.stanford.idm.oclc.org/10.4000/154ww 

Abstract: This article focuses on the used underwear market, defined as the market for underwear that has been worn by one or more individuals and sold unwashed, meaning it contains deliberately left secretions and fluids. It distinguishes websites where the nature of the product sold must be concealed (such as resale websites for secondhand items) due to the prohibition of the transactions, and websites where the product can be openly discussed (such as websites specializing in the sale of sexual items). This distinction allows for the study of the issue of product qualification and disqualification in a contested market, which has been hardly explored. More broadly, this article helps identify the main characteristics of an overlooked market that, until now, has only been the subject of sensationalist analyses. 

"this is a "contested market," that is, a market in which some people would like to carry out transactions, but third parties oppose them on the basis of moral considerations. This opposition can then translate into constraints placed on the organization of the market (Roth, 2007), such as its prohibition (e.g., organs), the prohibition of advertising (cigarettes), difficulties in obtaining a bank loan (pornography), the imposition of punitive taxes (sodas), or even the stigmatization of participants in the transactions. Contested markets have been the subject of a substantial body of literature over the past decade (e.g., Steiner and Trespeuch, 2014; Bertrand et al ., 2020; Bertrand and Panitch, 2024; Gradoz and Dekker, 2025), and this article proposes to analyze the used underwear market based on this literature, moving beyond the sensationalism that has prevailed until now. This literature has focused in particular on the justifications used by third parties to challenge the existence of certain markets, or on the strategies implemented by participants in transactions to cope with the constraints resulting from this challenge." 

Rent Control Creates Ghost Apartments

Adam Lehodey writing at City Journal:

In New York City, making a profit on real estate has become increasingly difficult. Rent-stabilization laws built on the mantra that “housing is a human right,” a dysfunctional housing court, and myriad other interventions have driven thousands of units off the market, giving rise to the phenomenon of New York’s “ghost apartments.”

The city now has nearly 50,000 empty units, absent from the market either because their operating costs exceed legal rents or because they require considerable renovations.

…Take a building on East 6th Street as an example. A mere five-minute walk from Tompkins Square, the building is a convenient home for students and young professionals.

One-bedroom units in the building average $3,500— except two of them, subject to the city’s rent-stabilization laws, which hold rents below $900 per month.

As a result, both units have been allowed to fall into disrepair, because the cost of restoring them to habitability is greater than what they’d generate in rent.

…Much of the predicament at the East 6th Street building and the apartments on Valentine Avenue can be traced back to one piece of legislation: the 2019 Housing Stability and Tenant Protection Act (HSTPA). Passed by a Democratic majority in the state legislature, HSTPA eliminated landlords’ abilities to raise rents after units were vacated, or when they exceeded $2,775 per month. In doing so, it also eliminated their ability to make improvements profitably and reset the stabilized rent.

Recall from the recent review by Kholodilin that “the published studies are almost unanimous with respect to the impact of rent control on the quality of housing….[namely] that rent control leads to a deterioration in the quality of those dwellings subject to regulations.”

Rocket Report: Russia pledges quick fix for Soyuz launch pad; Ariane 6 aims high

Welcome to Edition 8.23 of the Rocket Report! Several new rockets made their first flights this year. Blue Origin’s New Glenn was the most notable debut, with a successful inaugural launch in January followed by an impressive second flight in November, culminating in the booster’s first landing on an offshore platform. Second on the list is China’s Zhuque-3, a partially reusable methane-fueled rocket developed by the quasi-commercial launch company LandSpace. The medium-lift Zhuque-3 successfully reached orbit on its first flight earlier this month, and its booster narrowly missed landing downrange. We could add China’s Long March 12A to the list if it flies before the end of the year. This will be the final Rocket Report of 2025, but we’ll be back in January with all the news that’s fit to lift.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Rocket Lab delivers for Space Force and NASA. Four small satellites rode a Rocket Lab Electron launch vehicle into orbit from Virginia early Thursday, beginning a government-funded technology demonstration mission to test the performance of a new spacecraft design, Ars reports. The satellites were nestled inside a cylindrical dispenser on top of the 59-foot-tall (18-meter) Electron rocket when it lifted off from NASA’s Wallops Flight Facility. A little more than an hour later, the rocket’s upper stage released the satellites one at a time at an altitude of about 340 miles (550 kilometers). The launch was the starting gun for a proof-of-concept mission to test the viability of a new kind of satellite called DiskSats, designed by the Aerospace Corporation.

“The embrace of the unitary executive theory by both the president and the [Supreme Court] has given us the worst of all worlds: an ultrapowerful presidency without an actual president at the helm.”

Does the conflict between cardinal utility and ordinal preferences just keep on getting worse?

This argument is not necessarily a critique of capitalism, but it could be.  At the very least, it is an observation about advanced capitalism.

As you will know from philosophy, there is a difference between what makes you happy, in the felicific sense, and what you want.  Some of this difference may be due to addictions, but most of it is not.  You may want to be a person of a particular kind, whether or not that makes you happier.  You may wish to do things to help the world, without believing you will be personally happier as a result.  You might have mixed feelings as to whether having children will make you happier (stress!), but still you might have a deep preference for raising a family.  And so on.  These distinctions are part of the mainsprings of human life, they are not minor exceptions standing in the corner.

The more capitalism develops, the more the gap between cardinal utility and preference satisfaction is likely to grow.  Consider the polar case of a very primitive economy where the only commodity is rice.  Eating rice is what makes you happy, and eating rice is also how you wish to spend your money.  After all, what else is there?  Given the feasible set, cardinal utility and preference satisfaction will coincide perfectly.

But as product choice grows and incomes rise, you will have more and more chances to deviate from maxing out on cardinal utility.  Furthermore, your immediate “needs” likely are taken care of, so most of your income spending is discretionary rather than “I need to buy this food to avoid the miseries of starvation.”

More and more, you will be led away from cardinal utility maximization.  But additional preferences will be satisfied.

Is this good or bad?

It is not quite right to say that people are becoming less happy, as they are getting what they want.  That could be a central component of the good life, and of individual well-being, broadly construed.  That said, some of your ordinal preferences might be harmful addictions, or you might prefer things that stress you out, either proximately or in the longer run.

Let’s say you keep on checking your phone for texts.  Do you do this because you think it will make you happier?  Maybe not.  You simply might have a preference for wanting to know the information in those texts as soon as possible.  Should we think that preference is bad?  Maybe it is a mother wanting to know that her daughter got home safely, and so she checks her texts every three minutes.  That might not make her happier, but I am reluctant to conclude that is a worse state of affairs.  And it does not have to be an addiction, a much overused concept by intelligent people who do not define it very carefully.

I too have plenty of preferences that do not make me happier, though I consider them quite legitimate.  I am keen to see as much of the world as I can, yet I am not convinced this makes me happier than say simply going back to Mexico again and again and eating the street food.  I just want to know what else is out there.

If you side solely with cardinal utility, yes you condemn capitalism.  Or if you think all of these ordinal preferences are addictions, again you can condemn the status quo.  Your meta-preferences in that case presumably would wish to have different preferences.  In any case, many books will be written about how capitalism makes us miserable.  Most of them will have the incorrect framing, though most of them will have ” a point,” one way or another.  Furthermore, while some of these books may be correct, in the aggregate they will push us away from viewing individual human beings as agentic.  That is a negative social consequence.

I do not think those critical perspectives are, by and large, the primary correct views.  Instead, I think of capitalism and markets as an unparalleled engine for making us…weirder?  And for moving us into different worlds (NYT)?

YMMV.

Space Development Agency awards roughly $3.5 billion to 4 companies for 72 missile tracking and warning satellites

The U.S. Space Force’s Space Development Agency (SDA) awarded roughly $3.5 billion to four companies to begin building out the third generation of its low Earth orbit constellation.

The SDA issued firm fixed-priced Other Transaction Authority (OTA) agreements with L3Harris Technologies, Lockheed Martin, Northrop Grumman and Rocket Lab to build a total of 72 satellites for the Tacking Layer Tranche 3 (TRKT3) of the Proliferated Warfighter Space Architecture (PWSA) constellation in low Earth orbit.

“The Tracking Layer of Tranche 3, once integrated with the PWSA Transport Layer, will significantly increase the coverage and accuracy needed to close kill chains against advanced adversary threats,” said SDA Acting Director Gurpartap ‘GP’ Sandhoo. “The constellation will include a mix of missile warning and missile tracking, with half the constellation’s payloads supporting advanced missile defense missions to pace evolving threats.”

The satellites, which are slated to begin launching in fiscal year 2029 cover two types of sensing capabilities: missile warning/missile tracking (MW/MT) infrared (IR) sensors and missile warning, tracking, and defense (MWTD) sensors.

Each of the four companies will build 18 satellites. Here’s the breakdown of funds going to each company and which satellites they will build:

  • Lockheed Martin – $1.1 billion for 18 MWTD space vehicles (SVs)
  • L3Harris Technologies – $843 million for 18 MW/MT SVs
  • Rocket Lab – $805 million for 18 MWTD SVs
  • Northrop Grumman – $764 million for 18 MW/MT SVs

“The addition of these satellites will achieve near-continuous global coverage for missile warning and tracking, along with payloads capable of generating fire control quality tracks for missile defense,” Sandhoo said. “This is a prime example of spiral development: the ability to rapidly integrate the next generation of technologies, and to proliferate the most impactful capabilities for increased capacity and lethality.”

In its own announcement to its investors, Rocket Lab said that the initial amount is a base contract, adding that there are up to $10.45 million in options. The company said it would build these satellites on its Lightning satellite bus and feature “Rocket Lab’s next-generation Phoenix infrared sensor payload, a wide field-of-view (WFOV) solution designed to meet the evolving missile defense needs of national security space” as well as its “advanced StarLite space protection sensors, designed to safeguard the constellation against directed energy threats.”

Rocket Lab said some of the other companies on this contract were also incorporating its StarLite sensors.

“The Tranche 3 Tracking Layer constellation is part of the U.S. Space Force’s strategy to counter rapidly evolving global threats, ensuring the nation’s defense capabilities remain ahead of adversaries. Rocket Lab is honored to play a role in enabling this,” said Rocket Lab founder and CEO, Peter Beck. “Demand for resilient, scalable, and affordable space systems continues to grow, and this award demonstrates that Rocket Lab is uniquely positioned to lead the charge in delivering solutions that meet the needs of national security.”

This is the second SDA contract for Rocket Lab, adding to its $515 million award for 18 satellites with the SDA’s Transporter Layer-Beta Tranche 2 program. That will add “secure, low-latency communications across the PWSA.”

L3Harris is adding to its previous allotments of four missile tracking satellites that launches as part of the Tranche 0 part of the constellation and 34 satellites that are in development across Tranche 1 and Tranche 2.

The company recently opened a new facility on their Palm Bay, Florida, campus designed for production for their Tranche 1 and Tranche 2 satellites.

“L3Harris is proud to support SDA in its mission to deliver a next generation, layered defense architecture that can track threats in real time,” said Christopher Kubasik, Chair and CEO, L3Harris. “Defeating the hypersonic missile threat begins in space, and our Tranche 3 satellites will advance our proven, on-orbit tracking and targeting capability needed to protect our homeland.”

Northrop Grumman’s TRKT3 will build on the Tracking Layer capabilities of Tranche 1 and Tranche 2 with targeted technology enhancements, expanded coverage and increased integration including precision fire-control sensing. Image: Northrop Grumman

For its part, Northrop Grumman is now responsible for 150 satellites across the first three Tranches for the SDA. The first plane of its Tranche 1 Transport Layer (T1TL) satellites are set to launch “in early 2026.”

“Northrop Grumman’s contributions to both high and low altitude layers of our nation’s missile warning and tracking architecture help protect our nation from a wide range of threats,” said Brandon White, vice president and general manager of space-enabled multi-domain operations division at Northrop Grumman. “With our extensive history of fielding operational Overhead Persistent Infrared (OPIR) satellites, we are poised to rapidly deliver the TRKT3 satellites to the SDA.”

Lockheed Martin is receiving the largest piece of the contract pie for its 18 satellites. The company received a $890 million contract for 18 Tranche 2 Tracking Layer satellites in January 2024.

It launched 21 of its T1TL satellites in October 2025 with 21 more in production.

Lockheed Martin’s 18 TRKT3 satellites will be built on satellite buses from Terran Orbital. They will be built in Terran Orbital’s SmallSat Processing and Delivery Center in Colorado.

In total, Lockheed Martin is currently contracted to build 124 SVs for the SDA.

“Lockheed Martin’s ongoing investments and evolving practices demonstrate our commitment to supporting the SDA’s Proliferated Warfighter Space Architecture,” said Joe Rickers, vice president of Transport, Tracking and Warning at Lockheed Martin. “These innovative approaches position Lockheed Martin to meet the warfighter’s urgent need for a proliferated missile defense constellation.”

All of the satellites in the Tracking Layer will be designed to work seamlessly across all other satellites in the PWSA constellation in low Earth orbit in concert with a common ground system.

“The Tracking Layer will form a global constellation in LEO of IR missile warning and missile tracking satellites that integrate with the Transport Layer’s low-latency mesh communication network to provide mission data directly over tactical data links and enable advanced missile tracking from proliferated LEO,” the SDA said in a statement.

“Resilience is built in through proliferation by fielding refreshed capabilities with targeted technological enhancements approximately every two years with each generation of satellites that launch.”

Bondi Beach and the Shattering of Australia’s Egalitarian Promise

You arc a downhill left when you approach Bondi Beach from it’s south side, sloping into a horizon which peels away the rolling waves. Bondi Beach is it’s postcard picturesque. A vision of somewhere far away and hard to get to, but here it’s right around the corner. 

Bondi is centrally located, Australia’s most famous beach and rather than an oasis at the end of a journey it’s an organised hub of meeting. Life grows out of it rather than towards it. It’s a place mythologised by TV, a name known to every Australian. It’s even famous internationally, a gravitational pull to every backpacker, tourist or out-of-towner. It’s both a centrepoint for those that come, as it is a home to hundreds of families who claim generational lineage. 

As much as the Harbour Bridge, Uluru or even the Opera House, Bondi Beach is a symbol of Australia. It’s a placeholder for expectations. An idea for what Australian life is like. That great egalitarian instinct. No matter who you are, what you do, what you believe, how little or how much money you have the sea, sand and sun is equally yours to share. The terrorism denies that symbolism, is an affront to it. Hatred of Jews imported across generations and across borders. Grown elsewhere, ignorant of Australia, but nonetheless here. 

Bondi wakes up early, no matter the time, there’s people there. Dotting the sand, the waves, the promenade, the cafe’s, life is constant here. Irish voices, French accents, Germans, tradies, mums, dads, executives, politicians, everyone getting in a coffee, walk and work out before the day begins. 

Sunday the 14th was the summer’s day Bondi thrives on. It wasn’t oppressively hot and there was barely a lick of wind. The place was packed. Thousands of people scattered along the kilometre of sand, seated on the kilometre of grass and boozing and eating the stacking streets with faces of cafe’s, restaurants, bars and boutiques. 

That bridge, the one from the footage you’ve seen, from where the two gunman took aim, is a constant flow of traffic. It exits you from the north end of Bondi, connects you to the public changing rooms, and opens up to a particularly expansive grassy area. Events are routine and on Sunday it was no different. Hanukkah by the sea. An organised gathering of Jews, and to the shame of Australia, a target. 

A father and son combo who told their family they were going on a fishing trip fled to Bondi with a car full of guns, dressed with an ISIS flag, determined to kill as many people as they possibly could. An investigation into a motivation belies the reason. How powerful the Islamic fundamentalist brain rot is, so corrosive and sufficient the promise that this life is not the one you live for, it’s the next one, what you do here will determine how you’re treated there. A hopelessly broken belief system so ambitious in it’s reach yet evidently persuasive. 

As of writing this, 16 are dead (including one shooter) and more than 40 are injured. The shooting was indiscriminate. What began as a targeted flourish of bullets turned into a free-for-all. It’s too early for a full accounting for the damage but too late for a more unapologetic hard line. 

We’ve been impotently interpreting what religious fundamentalists within our border have been saying for years. Interpreting anything other than what it is. Rationalising it with a ‘that’s not what they mean’. Time after time, words and behaviour that completely deny Australia’s egalitarian instinct. Homes, mosques and gathering places festering idea’s of purpose and the life well lived that couldn’t run further against those of the land they stand on. Where is the Australian backbone to insist a loose conformity that we recognise? You can be both tolerant and reasonable. But I recognise nothing of Australia in fundamentalists, and was not prepared to cede ground to allow a splitting of the difference. Religious freedom isn’t in question here, it’s religious fundamentalism when your worldview clashes so severely with those around you, silo’d into narrower and narrower groups. A closed hole from where you began and where you were before the plunge. Evolving from a decent muslim to the one who runs away with his dad to murder kids.

One of the great benefits to our island nation is how tight a control we can enforce for who comes here and who doesn’t. Should you whiff of anything to do with a tendency towards religious violence, you’re free to find a home elsewhere. There is no place for you in Australia. If you congregate in public and chant ‘death to the jews’, you’ve punched your ticket. See you later. This would be radical policy, but we really are so far away from everything else that we can weather a political storm to much less damage were you to make the same policy elsewhere. 

Jews were targeted for slaughter at a children’s event at a symbolic image of Australia. How powerful the brain rot and how devastating we’ve let it fester.

Intermission: Battle Pulses

This week we’re going to take a brief break from our series on hoplites (I, II, IIIa, IIIb) to address a broader question in how we understand the mechanics of warfare with contact weapons, which is the mechanics of the concept of a ‘battle pulse.’ This notion, that front lines in contact might occasionally withdraw to catch their breath, replace wounded men at the front or simply to relieve the psychological pressure of the fighting keeps coming up in the comments and is worth addressing on its own. Because while it is an important question for understanding any kind of contact warfare (because ‘pulse’ proponents insist on the pulse as being a general feature of contact warfare, not restricted to any particular culture), it is both very relevant to understanding hoplites, but also emerged as an extension of the argument about othismos that extended into Roman warfare.

There is something of an irony that we are briefly disengaging from our discussion of hoplites to discuss if hoplites briefly disnegaged from battle.

So our question here is, “was the fighting at the point of contact between two formations of heavy infantry a continuous run of fighting or did it proceed in pulses and bursts and if the latter, of what nature might they have been?” I should note that the normal expression here is to describe the sparring at the line of contact as a ‘series of duels’ but anyone who has watched or participated in experiments in contact-line fighting will immediately recognize they are not ever a ‘series of duels’ as any given combatant on the front moving into measure is entering measure of several enemies and so may attack or be attacked by any of them (and indeed, striking the fellow to the left or right of the fellow in front of you, catching them unawares, is often useful). So the line of contact is not a series of 1-on-1s but rather a rolling series of ‘several-on-severals’ with each man having his own set of ‘several,’ depending on the length of the weapons used.

Now before we rush in, I want to make a clarification of two terms I am going to use here that might otherwise be confusing. I am going to make a distinction here between ‘measure‘ and ‘contact.’ This is not some well-established distinction, so I am bending these terms a bit to make clear a different that I think matters. When I say measure here, I mean the reach of the contact weapons the men have, how far they can actually deliver a strike. That’s going to vary a bit based on the weapons they have, but it’s going to be around 1-2 meters.1

When I say contact what I mean is a bit looser: two formations standing a few yards apart might be out of measure, but they are certainly in contact in that neither can maneuver freely and the men in the front of both must be focused on their enemies directly forward because anyone could dash into measure to strike at any time. For these units to move out of contact, I’d argue they need to back up a fair bit more, perhaps out to something like ‘javelin reach’ which with the heaviest of javelins might be around 20-25 meters. As we’re going to see, there’s a big difference between being just outside measure at perhaps 2 or 3 meters away and being at ‘javelin range’ at say, 15 meters away. But to be clear: measure here is the closer proximity, contact is the looser, more distant proximity.

But first, as always, if you like what you are reading, please share it as I rely on word-of-mouth to find readers!

Whence the Pulse

We ought to begin with a brief history of the concept of the ‘battle pulse’ in ancient warfare and fortunately this can be quite brief.

As you will recall from our historiography on hoplites and Michael Taylor’s guest post on the book, John Keegan’s The Face of Battle (1976) had quite an impact. It inspired Victor Davis Hanson to essentially replicate the approach in writing Western Way of War, kicking off the modern period of hoplite debates, but it also had imitators in the study of the Roman army, most notably Adrian Goldsworthy. Now I think it is worth noting that is something of an important delay here: when Adrian Goldsworthy goes to write The Roman Army at War, 100 BC – AD 200 (1997), WWoW (1989) has been out for nearly a decade and while the full-throated heterodox vision of Myths and Realities hadn’t arrived yet, it was clearly coming. By this point, in particular, Peter Krentz, writing article after article, had punched some pretty significant holes in elements of orthodoxy, including the shoving-othismos. So when Goldsworthy (and Philip Saban, working at the same time) go to apply a Keegan-style Face of Battle approach to the Romans, they are doing so downstream of the hoplite debate.

And so in a sense you want to understand Goldsworthy and Sabin (and Zhmodikov, to whom we will come shortly) as essentially the extension of hoplite heterodoxy into the Roman sphere; you can see this, I think, quite clearly in their writing (and in turn they are relied upon and cited by more recent hoplite heterodox writers). Except, of course, the scholarship on Roman warfare never had anything remotely as rigid or implausible as the ‘strong’ orthodox hoplite model, so the modifications to our understanding of Roman battle that these fellows offer are more modest.2

The starting point of this burst (dare we say ‘pulse?’) of Roman-legion-heterodoxy is P. Sabin, “The Mechanics of Battle in the Second Punic War” BICS 67 (1996), followed very rapidly be the aforementioned A. Goldsworthy The Roman Army at War, 100 BC – AD 200 (1997) and then clarified and restated with Sabin, “The Face of Roman Battle” JRS 90 (2000). Essentially Sabin raises the question first, noting that our sources often describe Roman battles in the Middle and Late Republic as lasting several hours (typically one to three) and noting that neither the number of casualties described nor the limits of human endurance would be consistent with a continuous exchange of sword blows for three hours. Hence, Sabin figures, the Romans must have moved in and out of contact, which in turn also helps him make sense of how battles in the Second Punic War seemed so often involve a formation getting ‘pushed’ backwards (not literally, of course) significant distances to create pockets or holes without collapsing. I should note that Sabin doesn’t really get into how far out of contact these movements might be.

Goldsworthy then brings to this problem the work of S.L.A. Marshall in Men against Fire (1947).3 Marshall had argued that only a small portion of soldiers in WWII had actually used their weapons, an extension of Ardant du Picq’s should-be-more-famous maxim, “Man does not enter battle to fight, but for victory. He does everything that he can to avoid the first and obtain the second.”4 Goldsworthy sought to apply this insight to Roman combat and argued that likewise in the front line of a Roman legion, many men, indeed “the majority of soldiers” even in the front rank must have done essentially no meaningful fighting, mostly staying safe behind their shields.5 It seems worth noting that this insight is being applied by analogy – no one ever had a chance to study contact warfare in this way – and so while I think there is an insight here going back to Ardant du Picq, it is not clear to me that the straight-forward application of very modern evidence of combat participation with guns can be applied to combat with contact weapons without considerable hazards. Goldsworthy also imagines Roman maniples – the basic maneuver unit of the legion in battle – more as ‘clouds’ of men fighting (a kind of presaging of van Wees’ skirmishing hoplites) rather than a coherent mass with men having a specific, assigned place in the formation. Instead, braver individuals might hype up the whole group to make a big push into contact, bringing the ‘cloud’ of soldiers forward, but men were equally able to hang back in the ‘cloud’ because there isn’t much sense of an assigned place.

But how to keep that up for a few hours?

The solution was the ‘battle pulse.’ Sabin imagines Roman battle as a “natural stand-off punctuated by period and localized charges into contact.”6 In this vision entire Roman maniples might functionally withdraw to javelin range for extended periods to catch their breath, exchange some missiles and recover. This is, in theory, a separate process from the Roman triple acies having the second (principes) and third (triarii) ranks move forward to take over the fight.7

So to be clear, what is being described here when we talk about ‘battle pulses’ is an action on the front line that consists of pulses and lulls, where in the lulls, the two lines withdraw out of measure (well out of measure, by implication) to momentarily rest and reconstitute, before the ‘pulse’ when one side rushes back into contact, precipitating another round of fighting.

This vision of battle then acquired key support with A. Zhmodikov, “Roman Republican Heavy Infantrymen in Battle (IV-II Centuries B.C.)” Historia 49.1 (2000). Prior to Zhmodikov, the general model for Roman infantry combat was ‘volley-and-charge:’ the hastati and principes advanced and hurled their pila at the outset of an engagement before closing in for a decisive action with swords. Zhmodikov instead pulls together all of the evidence for javelin use and argues that pila remained in use over the whole battle. This was in the moment pretty important because it solved a problem that Goldsworthy and Sabin faced which is that our ancient sources on battles almost never describe anything resembling the extended pause between pulses: we get pushes in the sources but not very often do we hear ‘lulls’ described (in stark contrast to their frequency in sources for gunpowder warfare, I might note). When a force is described as moving backward, it is generally because they are routing or being pushed, not because they are mutually disengaging. Zhmodikov’s article thus promised to provide an evidentiary basis that the Goldsworthy-Sabin ‘pulse’ model otherwise lacked, albeit quite indirectly so (‘these guys throw lots of javelins, so there must be pauses’ is not the same as ‘the sources tell us there are pauses.’)

But note that Goldsworthy and Sabin are seeking to explain Roman combat evidence and to do that they have resorted to general arguments about human endurance and psychology because they do not have much direct source evidence for the lulls in their pulse model (by contrast, I’d argue, the pulse itself – the ‘push’ – is attested). Consequently, this is a theory developed to explain Roman warfare, which was because of the lack of direct testimony in the sources is instead posited as a general rule of combat (since the only argument available is one from human endurance and psychological capability), from where it then gets applied to hoplites and dismounted knights and Landsknechte and so on. So we have to discuss it in this Roman context, but with a key warning: Greeks are not Romans and the Roman tactical and broader institutional military systems were not very much like Greek ones. Or, as Ardant du Picq quips:

The Gaul, a fool in war, used barbarian tactics. After the first surprise, he was always beaten by the Greeks and Romans.
The Greek, a warrior, but also a politician, had tactics far superior to those of the Gauls and the Asiatics.
The Roman, a politician above all, with whom war was only a means, wanted perfect means. He had no illusions. He took into account human weakness and he discovered the legion.
But this is merely affirming what should be demonstrated.

(It is not, in fact, clear to me that ‘The Greek’ had superior tactics to ‘the Asiatics’ by which Ardant du Picq means the Persians. The Macedonians certainly did, but that’s a separate question).

What Pulse

So given that scholarship, why aren’t my discussions of hoplite tactics or, indeed, Roman tactics, full of discussions of pulses?

Because I don’t think they were full of pulses, or more correctly, I don’t think they were full of what I am going to call macro-pulses, but they did include lots of what I am going to call micro-pulses, because I think it is important to distinguish between the two.

In a micro-pulse, what we’re really describing is ‘withdrawing to measure’ – the combatants separate not a huge amount, but just a few steps outside of the reach of their weapons (striking distance here is termed ‘measure’ so moving ‘into measure’ means moving into an opponent’s striking range (to strike yourself) and so too ‘out of measure.’) I don’t think two opposing lines locked shields against each other and stayed in measure for minutes or hours on end. That doesn’t seem physically or psychologically possible. It would produce the casualty problem Sabin identifies and psychologically, as Ardant du Picq points to, men are going to want to pull out of reach of their opponents weapons and that psychological force is going to become swiftly overpowering. Anyone who watches combat sports or HEMA sparring, as an aside, can see this tendency for fighters to pull out of measure but remain ‘in contact’ (close enough to move back into measure at any moment) for themselves.

So I have no problem with the ‘micro-pulse,’ and indeed, I think they must have been continually happening down the line, with men or groups of men stepping forward into measure to deliver one or two strikes (and likely take a few in return) before backing out. And of course that pattern might also serve to conserve the men’s stamina, because the periods of really intense physical action – the throwing of blows or blocks – might be interspersed with longer periods of watching and smaller probing strikes. I admit, it would be really interesting to see how long a set of reasonable fit reenactors could keep up this kind of pulsing fight, never withdrawing much more than a few steps beyond measure. The key would be running the experiment as near to exhaustion as possible, because we ought to expect battle to push men to the very limits of endurance as they struggle to survive.8

The broader question then is the macro-pulse, where we imagine the lines truly break contact to the point where they are far enough apart that men cannot dash forward back into measure quickly. Now Goldsworthy-Sabin-Zhmodikov don’t, to my reading, draw a distinction between these two sorts of pulses, so it is hard to tell which they mean, but when they talk about extended javelin exchanges late in battles or lulls long enough to switch out wounded or fatigued men I read that as a macro-pulse (or more correctly a ‘macro-lull‘). To the degree that these authors actually intend what I’ve defined above as a micro-pulse, then I don’t think I have any disagreement with them on this point. But instead what they seem to imagine is a battle that consists primarily of macro-lulls, punctuated by micro-pulses, where formations spend a lot of time at ‘javelin reach’ of each other (so separated by perhaps 10 or 20 yards instead of 10 or 20 feet).

Critically, such a large disengagement requires the whole formation to move. A micro-pulse can work by having the front ranks simply accordion into the back ranks, closing the ‘vertical’ distance between them, but a macro-pulse requires the rear ranks to really back up and critically for men to keep backing up after contact is broken and thus there is no immediate pressure from the enemy (because the macro-pulse also requires the enemy not to advance back to the edge of measure). Indeed, Sabin seems to imagine it is in the context of these macro-pulses that the Roman changing out of battle lines occurs, so we are really backing up quite a bit.

Fundamentally, the macro-pulse exists in tension then (via Zhmodikov) with a volley-and-charge model (which has no trouble incorporating the ‘micro-pulse’ – no one has ever suggested Roman soldiers did anything like a shoving-othismos). The macro-pulse model also generally asserts more flexible physical formation, approaching ‘clouds’ or ‘mobs’ of soldiers, rather than a single formation with assigned places and it isn’t hard to see how that makes sense if this formation is supposed to pulse forward and backwards; by contrast the older vision of volley-and-charge assumes a regular, somewhat rigid formation, not infinitely rigid as we’ll see, but there is at least the notion of a block of men who are intended for the most part to maintain relative position. In essence, this macro-pulse model assumes that these fellows are doing something closer to what we might call ‘dense skirmishing’ in ‘clouds’ rather than formations spending most of their time well out of measure for contact weapons. You can see how this works as a continuation of the hoplite-as-skirmisher ‘strong’ heterodox vision.

To put it bluntly, I think micro-pulses happen and are in evidence in the sources, however I think macro-pulses – situations where the two lines truly disengage for a period without either routing– seem very fairly rare and the source evidence for them as frequent occurrences is actually quite thin.

The Lull In the Pulse

And it seems like from some quarters when I express this view there is a degree of incredulity that I would ‘go against the scholarship’ on an issue that is treated as ‘solved.’ Which is odd to me because it seems clear that significant parts of the Goldsworthy-Sabin-Zhmodikov thesis have been softened or even overturned.

An effort to find Goldsworthy’s pulses-and-lulls in the sources was mounted by Sam Koon, Infantry Combat in Livy’s Battle Narratives (2010).9 Koon set out to find the lulls though it is striking that the clearest example of a lull is also obviously exceptional: the two-part battle at Zama (202), where the ‘lull’ is very openly and visibly created by the recall of the hastati behind the next line and the re-ordering of the formation, rather than by a pulse-and-lull model; we’ll come back to this. And there is certainly some openness to this model. I am stuck, for instance by two chapters in The Oxford Handbook of Warfare in the Classical World (2013), eds. B. Campbell and Lawrence Tritle: Michael Sage’s chapter (“The Rise of Rome”) which accepts the Goldsworthy-Sabin-Zhmodikov model and Brian Campbell’s chapter (“Arming Romans”) which implicitly rejects it, asserting a volley-and-charge purpose for the pilum. But problems with the macro-pulse model emerged.

For one, some of the spacing and interval problems that Sabin brushed off as unsolveable (and thus avoids having to account for even flexible-but-real intervals and formations) have been revisited by MT. Taylor, “Roman Infantry Tactics in the Mid-Republic: A Reassessment” Historia 63 (2014) and to a significant degree resolved: there is a regular formation, it has both close-order and modestly-open-order standard intervals and we can also gauge to a significant degree the intervals between maniples. The units of the army (and the army itself) were accordions, not clouds of soldiers and men could – and in the sources do – close up to receive missiles or space out to fight in close combat (typically, we’ll get to this, they do the one and then the other). Most notably, the intervals between maniples are almost certainly – at points explicitly (Sall. Jug. 49.6) – where the light infantry (like the velites, but also any slingers or archers) are, which in turn exposes a real weakness in Zhmodikov, which is a near-total failure to distinguish between heavy infantry throwing their pila and the light infantry velites throwing their lighter javelins (hasta velitaris). The heavy infantry have just two pila, but the velites carry many javelins, which as you might imagine has implications for extended missile exchanges and intended function.

But crucially, Taylor’s approach fatally undermines the notion of the maniple as a ‘cloud’ of soldiers: these men have assigned spaces and semi-standard spacing with clear intervals between them. Polybius – who we must stress describes standard spacing in this army which he was an eyewitness to (18.30.6-8) – is not making it up. Instead, Taylor’s formation is not a cloud but an ‘accordion’ – the men have assigned spaces in which they are free to move around. Each man thus has some flexibility of position, but not infinitely so. That accordion nature can accommodate ‘micro-pulses’ but for a macro-pulse you have the problem above: it requires the rear ranks to back up quite a bit.

That point about distinguishing who is throwing the javelins in turn becomes the cornerstone of J.F. Slavik, “Pilum and Telum: The Roman Infantryman’s Style of Combat in the Middle Republic” CJ 113 (2018) which argues that the velites use showers of their light javelins -to enable the changing out of hastati to principes or triarii. Zhmodikov fails to distinguish the activity of the velites and so as a result his battles of “long exchange of throwing weapons”10 functionally collapses into the action not of Roman heavy infantry, but of Rome’s dedicated light infantry skirmishers, operating in those intervals noted above. I don’t know that Slavik’s philological argument – that we can distinguish what is being thrown and thus who is throwing it by the words used – is airtight, but in the cases where we are told explicitly what kind of soldiers are doing what, his argument holds much better: heavy infantry seem to volley-and-charge, while the velites and other lights may be skirmishing on a more extended basis in the intervals and covering the line-changes.

That said, whereas the heterodox/orthodox line on hoplites has tended to be a hard division into two camps, thinking on the Roman army, has tended much more towards synthesis, in part because the individual questions (role of the pilum, the extent of skirmishing, the presence of ‘pulses,’ the rigidity of the formation) are not treated as forming a coherent orthodox/heterodox, but rather ‘sliding’ values capable of moving independently. You can see this in general treatments, e.g. K.H. Milne, Inside the Roman Legions (2024), which clearly asserts a volley-and-charge model of pilum usage (163) and a clear sense of a “static front line” implying a regular formation (159, 162) with assigned places (166) but frequent micro-pulses (164, 167), but no macro-pulses except for the changing out of lines (167), with most fighting done with swords, not pila and supporting missiles to cover these movements by velites, not heavy infantry (168). It’s a blended position. At some point it is hard to say if that is either a very softened version of volley-and-charge or a softened version of Goldsworthy-Sabin-Zhmodikov, because we’ve more or less met in the middle.

So What of Battle Pulses?

So I do not think the scholarship at present requires me to adopt the complete Goldsworthy-Sabin-Zhmodikov model. And, as it is clear, I don’t entirely adopt that model, though I don’t think everything about it is wrong either.

In particular, I do not think macro-pulses, as I’ve defined them, were common, as distinct from the ‘micro-pulse,’ which I think must have been continuously happening, where the lines remain loosely ‘in contact’ (within maybe a few yards of measure) or the ‘line change’ (from hastati to principes to triarii), probably covered not by pila but by velites throwing their hastae velitares.

Now I am not going to reproduce Koon’s book going in the other direction in a blog post – and in any case, one of the authors above is already working on a monograph on Roman tactics which I shall not spoil here – but I want to give a few data-points as to why I lean this way.

The first is the soldier’s oath Livy reports before Cannae (Livy 22.38.4), “that they would not go away nor drop back from their posts [ex ordine] neither for flight or fear, unless to pick up or fetch a weapon, or to strike an enemy or to save a citizen.”11 The word ordo in that sentence (ex ordine) means a row, a line, a series, a rank, an arrangement of things, but it is not a unit and it is certainly not a ‘cloud.’ It is an assigned place that the soldier is bound to. The oath, which Livy represents as customary and regular, makes no sense unless these soldiers have an assigned place in their unit to which they can swear not to leave nor even to shrink back from (non…recessuros, “not to withdraw from, shrink back from, fall back from, give ground”).

Meanwhile, we have a lot of evidence, I’d argue, as to the volley-and-charge nature of pilum use. We get lines like, “When he [the Roman commander] was leading the men-formed-up from the camp, scarcely before they cleared the rampart, the Romans threw their pila. The Spaniards ducked down against the javelins thrown by the enemies, then rose themselves to throw [their own] which when the Romans, clustered together as they are accustomed, had received with shields densely packed, then, with foot against foot and swords drawn, the matter was begun” (Livy 28.2.5-6), which is just a very clear statement of a volley-and-charge action, the throwing of pila by the Romans in the perfect (coniecerunt, ‘perfect’ meaning ‘completed’) tense: it happened (once) and then stopped.12 Further examples of volley-and-charge in Livy are not hard to come by.13 Heck, Tacitus has a Roman general lay out the sequence in an order to his men: “with pila having been thrown then with shields and swords continue the butchery and slaughter” (Tac. Ann. 14.37).14

Most striking are the incidents where the Romans don’t throw their pila at all. Livy, for instance, has one general, the dictator Aullus Cornelius Cossus, tell his men to drop their pila and then note that the enemy (the Volsci who will have fought in the same manner as the Romans), “when they shall have thrown their missiles in vain” will have to come to close quarters where he expects the Roman line will triumph (Livy 6.12.8-9). Conversely, Q. Pubilius Philo’s troops are so eager on the attack that they drop their pila to engage directly with swords (Livy 9.13.2, cf. also 7.16.5-6, this happens more than once). Likewise, Julius Caesar reports in one battle that, “Thus our men, the signal having been given sharply made an attack on the enemies and they charged the enemies so suddenly and rapidly that a space for throwing pila at the enemy was not given. So throwing away their pila, at close-quarters they fought with gladii” (Caes. BGall. 1.52.3-4). It happens in Sallust too (Sall. Cat. 61.2).

If these guys think they are regularly going to back off out of close-combat to throw javelins for a bit, why do they drop their javelins (pila) the moment they come to close quarters? Surely, if having a ‘macro-lull’ was normal, they would want to save these weapons – at least in the back ranks – to be available in that event. Instead, the expectation is clearly not that the unit will back off after it has engaged nor that men in the rear ranks are throwing pila over the heads of the men in front of them (the danger of which is noted in some ancient sources, e.g. Onasander 17).

Now for the man in the front the answer is pretty obvious that pila are quite heavy and you can’t sword-fight while carrying them and a shield and so they have to go if youa re coming to close contact. But note that these lines don’t say “and then the front rank dropped their pila” but rather clearly whole units do. Which really only makes sense if these fellows imagine that once they are going into contact, they are not going to break contact for more missile-throwing or just to sit outside of contact.

We might also consider what we know about Pydna. Now this relies a fair bit on Plutarch and Plutarch is often not the best source on battles, but on Pydna he is working from some known sources (Scipio Nasica Corculum’s writings and likely the account of Polybius) and his vignettes are instructive. By the time the general, Lucius Aemilius Paullus is on the field – this was, you will recall, an unplanned engagement – the armies are already to close combat (Plut. Aem. 18.4) and we’re given a really physical description that the sarisae of the Macedonians were fixed in the shields of the Romans (19.1) so we know he intends us to understand these units are very much in contact (though we’d say that while the Macedonians are in measure, the Romans are not). Certainly no one has backed out of contact.

Then we get two interesting passages which I think we might say are something like micro-pulses: a Paelignian chucks his unit’s standard into the enemy to compel them to make a push (20.1-5) and after taking heavy losses, they’re pushed back but evidently still to some degree in contact (perhaps pursued) because – as Michael Taylor notes in his reconstruction of the battle – they continue to hold up the Macedonian agema which would otherwise flank the legion. Meanwhile we also get Marcus Cato (son of Cato the Elder), who loses his sword and has to gather up his friends to push forward to retrieve it (21.1-5). In both cases these are units that we have to understand are in contact, not back at javelin reach, where an individual is rallying men to push forward in an effort to force the enemy back: Marcus Cato’s effort succeeds, whereas the Paelignians are thrown back (but buy essential time for the main Roman force). Both of these events have to involve units that are outside of measure, but which do not seem – note the above line about pikes touching Roman shields – to be fully out of contact.

The battle is won, as Livy (44.41.6-9) and Plutarch (20.7-10) both note, by having the Roman maniples engage separately, exploiting disruptions in the phalanx as it advanced. What I find striking here is that our sources – both relying on the (lost) Polybian account of the battle – evidently think that this ‘engage at discretion’ order needed to be given as an order (Plut. Aem. 20.7-9); dropping well back out of contact was evidently not a thing units normally were not supposed to do on their own. If engaging at discretion like this was the standard way of fighting, there would be no point in Plutarch having Aemilius order it, or Livy noting the unusual nature of many separate engagements.

We can contrast what we’re told about the Battle of Zama, which gives us a very clear macro-scale battle lull, albeit an unusual one (Polyb. 15.13-14). Both armies are drawn up (after Roman fashion) in multiple battle lines; the first lines of the two armies, the Carthaginian mercenaries and the Roman hastati engage in a fierce close-combat fight, but separation doesn’t occur as a result of a macro-battle-pulse, it occurs because the mercenary line collapses after the failure of the Carthaginian second line to move up to support it (Polyb. 15.13.3-4; the impression is psychological collapse, as Polybius is noting the cheering and encouragement of the so-far entirely unengaged Roman second line as decisive). The mercenaries collapse into the main Carthaginian line, which does not admit them, leading to a mercenary-on-Carthaginian engagement in which the fleeing mercenaries are slaughtered by their employers (Polyb. 13.5-6), which in turn now leaves the field of gore and wreckage between the Romans and their enemies (Polyb. 14.1-2). Scipio doesn’t want to advance over that so – and this is the thing – “recalling those still pursuing of the hastati by trumpet” [emphasis mine] Scipio reforms his ranks (Polyb. 14.4).

What is significant to me here is that the disengagement of the hastati is not voluntary or automatic or natural, but in fact requires a trumpet signal: Scipio has to order an army-wide ‘pause’ in order to reorganize his units (really, he is ordering the ‘change out’ of the hastati as a way to halt their pursuit), which he can do in part because the peculiar situation where Hannibal (himself seemingly mimicking Roman tactics he has by this point so much experience with) has not yet committed his main line of infantry. This thus isn’t an organic ‘macro-lull’ so much as it is both armies attempting to the classic Roman hastati to principes line change, with the Romans doing it more successfully because their fussy tactical system creates lanes, whereas Hannibal needs his mercenaries to run all the way around his second (unbroken) line to get off of the field.

I think this episode should also give us some meaningful pause when trying to apply Roman tactical thinking outside of Roman contexts. The Roman system of maintaining multiple complete lines of heavy infantry, one in contact initially and two out of contact is, if not unique, certainly unusual. Likewise, a formation with wide, relatively regular intervals to enable the front battle line to be ‘changed out’ in a regular fashion is again, if not unique, highly unusual. Efforts to mimic that flexibility without the same complex and unusual tactical system often went badly, as with Hannibal’s mercenaries at Zama or, famously, the French dispositions at Agincourt, where an advanced cavalry force disrupted the two main lines of infantry attack15 as they advanced and then those lines, with no way to interchange, stacked up on each other to their ruin.

But it is also indicative of how unusual a ‘macro-lull’ was: this one only happens because Scipio Africanus gives an order to recall his front line as the enemy’s front ranks were breaking. Once again, the reason the armies end up separated after a ‘pulse’ of violence is not because that was the normal way these armies fought but because one general had specifically and somewhat unusually ordered it.

The other example of a large-scale macro-lull is equally instructive: Appian BC 3.68. Appian is describing an engagement between two veteran Roman legions at the Forum Gallorum (43 BC). Reading the passage, I think it is obvious we should not take the engagement as anything like typical: they fight in silence, no battle cries but also cries or shouts even as men were wounded and killed. Each man who falls is instantly replaced, every blow was supposedly on target. And in this context of a literary description of inhuman mechanical precision in battle, we’re told “when they were overcome by fatigue they drew apart from each other for a brief space to take breath, as in gymnastic games, and then rushed again to the encounter.” Immediately after that, we’re told the other soldiers present were taken by amazement at the sight and sound of it. It is a description that is clearly heavily embroidered, about a battle where Appian is writing nearly two centuries after the fact, about an army that is supposed to seem superhuman in its actions through the motif of presenting the soldiers as treating the battle like gymnastic games. I do not think we can draw secure conclusions about actual battlefield practice from such a passage alone.

After this, I should note, we swiftly begin running out of examples of clear ‘macro-lulls’ in Roman battles. Plenty of units being ‘pushed’ (discussed below) or collapsing under pressure or armies being flanked experiencing crowd collapse under continuous pressure (e.g. Cannae), but almost no examples of units engaging and then backing off and then moving back to re-engage.

The Roman Face of Battle And Implications for Hoplites

Summing all of this up, what do I think a Roman maniple engaging in pitched battle combat against heavy infantry looks like, given the evidence?

The attack begins with the volley of pila and it sure seems like usually any pila not thrown at this point are discarded, given how often we hear of pila being dropped without being thrown.16 We’ve already discussed the weapon and its performance and so need not belabor the point here.

The hastati follow this with a charge to contact with swords. A few things could happen at this point. One side could collapse, leading to rout and slaughter, of course. Alternately, both sides might stand firm: the Romans are heavily armored and have big shields and many of their opponents have big shields (if generally lighter armor) too, so a lot of strikes are going to not connect, or merely graze targets. Our ancient sources assume quite a lot of non-lethal, non-disabling wounding happening in these battles and we ought to believe them, given shields, armor, and movement. If both sides stay firm then after a few blows we might expect them to ‘accordion’ out to measure as men refuse to stay inside of the ‘killing zone’ a few feet wide running along the line, a ‘micro-lull’ in which the units are still in contact, but much of their front lines are not in measure.

On either side, the soldiers now need to move up to advance into measure in order to strike, but in this model they can do so with just a step or two. Because this is a formation with a regular order, the men in the front cannot simply drop back for fear – recall, they have sworn not to do so – and the eyes of their buddies are upon them, which is one of those things that can get men to fight when they might otherwise not, though one imagines many of the blows are very tentative and a high proportion of the total time here is spent watching and waiting. Sabin is right about that: it basically must be given the relatively low casualties in these periods and the fact that they might stretch on for many minutes even to an hour or more in some cases.

The men in the front are being cheered on by their fellows behind them and at least in the case of the Romans also urged forward by their centurions and it is this context where you get the micro-pulses: individuals or more likely groups of men push forward into measure for a concerted ‘push’ on the enemy line. They’re not literally shoving, of course, but simply moving aggressively into measure to attack – in the case of the Romans they have to move well into measure because they have swords and not spears, so they are relying on their heavy armor and big shield to absorb a strike from the enemy before they can reply. On the other hand, once they get through that range, they are significantly more lethal, better able to strike over or under an enemy’s shield and pierce armor. It’s a ‘high risk, high lethality’ tactical package that the Roman soldier carries, balanced with his heavier-than-typical armor and shield.

Now the enemy can do two things: they can hold firm against this ‘push’ or – seeing friends fall and feeling the danger – they can push back out of measure on their side, backing up to get space. This isn’t a rout yet, cohesion is not broken, they’re just going to back up into the empty space between them and the next man behind them and that man will then back up too to preserve space as the formation accordions in from the front, then accordions out again on the back. This probably isn’t a huge movement – it doesn’t need to be. A quick shuffle of a yard or two is enough to clear well out of measure. At which point the Romans can press again or stop at measure to stabilize.

Now what often happened, what Hannibal is counting on at Cannae, is that this process is going to repeat over and over again, steadily pushing a line backwards without breaking it. The Roman, after all, has the shorter range weapon – he must, on some level, advance or he has to endure ‘potshots’ from longer spears forever. And he can advance, trusting his large shield and heavy armor to absorb a blow or two from his enemy while he pushes into his own, shorter but more lethal measure. So when the enemy backs up, the Romans quickly – perhaps immediately – push right back into measure. A few more foes fall, the enemy backs up again. After all, his enemy lacks that heavy armor and big shield to be so confident in very close quarters and so will want to move away from the Roman with his deadly sword, back to spear’s reach. So long as cohesion holds, each localized ‘push’ is perhaps only gaining a few meters and neither side is breaking contact, but the line is bending and moving. Roman maniples can adapt well to that shifting line; the sarisa-phalanx cannot (thus Pydna).

In this sort of back and forth, I think we need to assume that wounded men (or utterly exhausted ones) can drop back through the ranks, but there’s clearly some shame in so doing, at least for the Romans (remember that oath). But there’s plenty of space with a Roman file width of c. 135cm. Heck, even at a conjectured hoplite phalanx’s 90cm, a hurt man could squeeze back – or be pulled back – by his comrades so long as the formation is hovering at the edge of measure rather than right up on the enemy. Cycling the front rank seems to have never been systematized, however, so I suspect the expectation is that many men in the front ranks will remain there through the whole fight if they’re not wounded.17

Because the line’s movement forward and back is driven mostly by psychology, it is a visible indicator of the more confident side – the side with confidence is pushing into measure, their opponents backing out. For many armies using contact weapons, there’s not much a general can do at this stage even if they see that their line is getting the worst of it, but Roman armies are unusually complex and so the Roman general has an option here if things don’t seem to be going well: he can sound that trumpet to recall the hastati. What I suspect happens here is that the men at the front are going to – still facing the enemy with shields up – quickly shuffle backwards (getting out of measure and moving to exit contact) while the velites (present in the gaps of the formation) shower javelins to give their opponents pause and then everyone breaks for the rear, passing through the intervals of the next line. The enemy cannot charge after them or they’ll run pell-mell into the well-ordered maniples of the principes and be butchered. Surely this must have entailed the loss of some of the hastati, but not many, I’d imagine, with the velites covering (and the velites, very lightly equipped, can easily flee an enemy’s heavy battle line).

The centurions rally the hastati in the safety of the space behind the principes, who now advance and the cycle repeats.

So micro-pulses but not macro-pulses: the lines once in contact don’t break that ‘loose’ contact except to flee, but they do ‘push’ and while there is no general pause in fighting, individually soldiers are not always swinging or being swung at.

What might that mean for a Greek hoplite phalanx? Well quite a few of these elements must substantially drop away. While the Greeks certainly have light infantry, as we’ve discussed they do not have integrated light infantry, nor the retreat lanes or tactical flexibility to use them in the way the Romans do; Greeks are not Romans. Equally, while the phalanx has a bunch of organizational units, it does not have a lot of maneuver units: the whole formation is supposed to move together. So the ability to maintain cohesion moving in and out of contact is going to be significantly less. And there is no way to change out entire battle lines, both because the phalanx is not built to do so and also because there is no second battle line waiting to rotate in any case.

But the other elements, I think, largely remain. No volley of pila (at least, not after the Archaic, but we must assume that earlier Archaic throwing spear fills a similar role to a pilum, a pre-charge volley weapon), but the hoplites charge to contact (as noted last time, either to measure or to impact). But they don’t start shoving, instead accordioning back out and then, as above, the micro-pulses: localized ‘pushes’ in sections of the line. In some cases, you might get the ‘pushing’ effect we see the Romans achieve although it is notable to me that it seems like hoplite armies achieve this effect less (though certainly not never!) and I suspect this is because everyone is working with a spear’s reach and thus a spear’s measure, so no one side is compelled (as the Romans are) to advance impetuously through an opponent’s measure, nor is one side (as Macedonians might) able to relentlessly push an enemy back from beyond their measure. But I don’t think the lines frequently disengaged in the Classical period, because we’re not told that they do so in any source I can think of and because the phalanx would be even less capable of doing a ‘macro-lull‘ than a Roman legion and it seems like the Roman legions almost never did them either.

The consequence of this model – micro-pulses but no macro-lulls – is to a degree to restore the role of heavy infantry as ‘shock’ based contact troops. These men – and I think this is true of hoplites as well – fight in formation, with assigned positions (or something very close to it) that they are expected to maintain for as long as they are able. Once they advance into contact, they do not expect to break contact until one side has won or lost the fight in that part of the line. But they do not stay permanently in measure swinging potentially lethal blows for an hour straight. Instead we might imagine an open space, roughly the width of measure (so a couple of meters), with men lunging or advancing forward to strike and then backing out. Every so often a concerted group of men will push into measure collectively. And sometimes their aggression causes the enemy to back up, leading to the ‘pushing’ effect we’re told about – which happens with no shoving.

But what they are not doing is backing out to go back to skirmishing. The reason so many javelin-wielding line infantry (archaic hoplites, Roman heavy infantry, Iberian and Celtiberian infantry) carry just one or two javelins is that they expect to hurl these immediately before contact to intensify the force of their onset and then not do any more throwing. If these units break contact, it is because they are routing or – in the Roman case only – because they have been recalled to reform behind the next line of heavy infantry. But heavy contact infantry are not skirmishers and so we should not try to extrapolate their behavior entirely from watching the fighting of Dani skirmishers in Papua New Guinea. Our sources resound with assertions and descriptions that heavy infantry worked differently on the battlefield than light infantry and that the two types were not interchangeable.

Hopefully that all clarifies my views on ‘pulses’ and ‘lulls.’ Micro-pulses? Yes. Macro-lulls? Only very rarely, in unusual circumstances.

Now as I write this, I am getting ready to fly out to attend the 2025 Prancing Pony Podcast Moot to deliver a keynote on the historical grounding of Tolkien’s view of war. Next week is also the week of Christmas. So there will be no post next week (the 26th), so we’ll be wrapping up our look at hoplites in the New Year.

Friday 19 December 1662

Up and by appointment with Mr. Lee, Wade, Evett, and workmen to the Tower, and with the Lieutenant’s leave set them to work in the garden, in the corner against the mayne-guard, a most unlikely place. It being cold, Mr. Lee and I did sit all the day till three o’clock by the fire in the Governor’s house; I reading a play of Fletcher’s, being “A Wife for a Month,” wherein no great wit or language. Having done we went to them at work, and having wrought below the bottom of the foundation of the wall, I bid them give over, and so all our hopes ended; and so went home, taking Mr. Leigh with me, and after drunk a cup of wine he went away, and I to my office, there reading in Sir W. Petty’s book, and so home and to bed, a little displeased with my wife, who, poor wretch, is troubled with her lonely life, which I know not how without great charge to help as yet, but I will study how to do it.

Trump commits to Moon landing by 2028, followed by a lunar outpost two years later

A couple of hours after a judge formally swore in private astronaut Jared Isaacman as the next administrator of NASA on Thursday, President Donald Trump signed an executive order outlining his space policy objectives for the next three years.

The executive order, titled “Ensuring American Space Superiority,” states that the country must “pursue a space policy that will extend the reach of human discovery, secure the nation’s vital economic and security interests, unleash commercial development, and lay the foundation for a new space age.”

White House sets priorities

There is nothing Earth-shattering in the new executive order, as much of it builds on previously announced policies that span multiple administrations. There are some notable points in the document that clearly reflect the White House’s priorities, though, and Isaacman’s leadership of NASA.

Russia is about to do the most Russia thing ever with its next space station

For several years now, in discussing plans for its human spaceflight program beyond the International Space Station, Russian officials would proudly bring up the Russian Orbital Station, or ROS.

The first elements of ROS were to launch in 2027 so it would be ready for human habitation in 2028. Upon completion in the mid-2030s, the station would encompass seven shiny new modules, potentially including a private habitat for space tourists. It would be so sophisticated that the station could fly autonomously for months if needed.

Importantly, the Russian station was also to fly in a polar orbit at about 400 km. This would allow the station to fly over the entirety of Russia, observing the whole country. It would be important for national pride because cosmonauts would not need to launch from Kazakhstan anymore. Rather, rockets launching from the country’s new spaceport in eastern Russia, the Vostochny Cosmodrome, would easily reach the ROS in its polar orbit.

Two space startups prove you don’t need to break the bank to rendezvous in space

It may be happening quietly, but there is a revolution taking place with in-space transportation, and it opens up a world of possibilities.

In January, a small spacecraft built by a California-based company called Impulse Space launched along with a stack of other satellites on a Falcon 9 rocket. Upon reaching orbit, the rocket’s upper stage sent the satellites zipping off on their various missions.

And so it went with the Mira spacecraft built by Impulse, which is known as an orbital transfer vehicle. Mira dropped off several small CubeSats and then performed a number of high-thrust maneuvers to demonstrate its capabilities. This was the second flight by a Mira spacecraft, so Impulse Space was eager to continue testing the vehicle in flight.

The Surprising Return of the Bookstore

Three years ago, I praised the new boss at Barnes & Noble—a man named James Daunt who actually loves books. Back then, he was already infusing new life in the struggling company, and I predicted good things to come.

They have now arrived in full force.

Barnes & Noble opened 57 new stores in 2024 and 58 in 2025. Plans are afoot to open 60 more stores in 2026, and list the company on the stock exchange.

This is a remarkable achievement. It’s happening in the face of eroding reading skills and the replacement of leisure reading with online distractions. Reading for pleasure is down 40% but Barnes & Noble is growing steadily. James Daunt must be some kind of culture superhero to succeed in this environment.

How does he do this?

Barnes & Noble building in Union Square in Manhattan (Source)

His goal is simple and straightforward: He wants to “make the bookstore as interesting and attractive as possible, and have within it friendly, informed booksellers who enjoyed their customers and their jobs.”

Daunt cares deeply about books and hires people who feel the same way. Then he enlists the support of booksellers in individual stores—who are given more freedom now to promote works they love. He even stopped taking promotional money in order to focus on the quality of the book instead of kickbacks from publishers.

This is how it’s done. Others in the culture business could learn from Daunt’s example.

I’ve often praised Taylor Swift for how she deals with business issues—and even published an open letter to her, asking her to get more involved in these matters.

So I am happy to report that she has done me proud once again. She gave out $197 million in bonuses to her crew—not just the people on stage, but also truck drivers, caterers, lighting staff, and other workers behind the scenes.

That’s a meaningful portion of her bottom-line profits from her tour. I don’t believe any music star in history has done anything even close to this.

As many of you know, I believe in karma—and not just as a pop psychology concept. Karma exists and is embedded in the fabric of the universe. (I explained some of my thinking about this matter here. But I need to write about this in more detail in the future.) So it makes cosmic sense that the most generous performer in music is also the most successful in her own endeavors.

We will see a reverse example below—where I discuss the state of play at Billboard magazine.


Meanwhile, Swift’s ability to tap into new income streams continues to amaze me. For example, I saw this at the checkout counter of my local supermarket.


The absurd havoc produced by AI is a regular theme at The Honest Broker—and there is never a shortage of them. But the latest idiocy deserves its own reality show.

The farce began when Anthropic decided to test a vending machine powered by AI—which would manage inventory and prices, while responding smartly to consumer demand.

The company was so proud of its work that it asked the Wall Street Journal to test the machine in its own office.

That was a bad move. Here’s what happened next:

Within days, Claudius had given away nearly all its inventory for free—including a PlayStation 5 it had been talked into buying for “marketing purposes.” It ordered a live fish. It offered to buy stun guns, pepper spray, cigarettes and underwear….

The AI vending machine soon went broke—which might also happen to some of these AI companies in the near future.


I first warned that old music was killing new music in an article that went viral back in 2022. But the situation has gotten much worse since then. Old songs are now so popular that it’s an embarrassment to the music industry.

Billboard is so concerned about this that it has now changed the rules for inclusion on the Billboard chart. According to NPR:

Billboard has revised its system of removing songs from the Hot 100 singles chart once they’ve gotten too old to qualify as contemporary hits. The measure, intended to shorten the amount of time successful songs spend on the Hot 100, knocks 10 tracks off this week’s chart—including Swims’ “Lose Control,” which spent more than two years on the Hot 100.

I understand why Billboard is doing this. But it’s not a satisfying solution to the real problem. It merely pretends that our music culture isn’t stagnating.

What we really need is for the music industry to invest in developing new talent. The scene would look much brighter if major labels took a fraction of the money they spend on buying publishing rights to old songs, and focused that on emerging artists.

But they have no intention of doing that—so they deserve all the long-term problems they are creating for themselves.


By the way, one of those ugly problems just landed on Billboard’s doorstep.

And here’s a headline from today—possibly related to the above shenanigans.

Yes, karma is real….

Almost twenty years ago, I started babbling about prehistoric cave art—and said that music scholars need to pay close attention to the acoustics in those caves. These vivid paintings are almost always located in the part of the cave with the greatest resonance. This tells me that singing and chanting took place in these locations.

Cave art from Lascaux in France (Source)

Now a seven-year study has proven this irrefutably.

“I was completely amazed,” says archaeologist and project leader Margarita Díaz-Andreu at the University of Barcelona, Spain, recalling her experiments at Valltorta gorge in eastern Spain. “Before the paintings, there was barely any reverberation, but as soon as we reached the paintings, the sound changed immediately.”

My hypothesis is that hunters gathered in front of these cave paintings in preparation for their expeditions. They sang here, and the acoustics created loud powerful sounds that gave them courage for the hunt—and also scared away larger animals, thus allow the humans to operate as scavengers.

This was, needless to say, the first rock music—surrounded by actual rocks.


I keep worrying about what tech is doing to our thinking and reading skills. But some businesses are already prepared.


That’s all for now. I’ll be back soon with more.

Condensed Serif Typefaces, à la Apple Garamond, Are Back in Vogue

Katie Deighton, reporting last month for The Wall Street Journal:

Henry Modisett wanted his employer to stand out. Competitors of the artificial-intelligence firm Perplexity were embracing their science-fiction roots with futuristic branding that felt cold to him. So Modisett, the firm’s vice president of design, looked to the past.

He plowed through graphic-design books and tomes of logos featuring obscure examples like Hungarian oil companies from the ’80s. But he kept coming back to a slender, bookish typeface famously used in Apple’s “Think Different” campaign. Modisett in 2023 began slipping a cousin of the font into Perplexity’s software and marketing materials.

“It felt fresh,” he said.

Not anymore.

Apple’s custom variant of ITC Garamond was called, appropriately enough, Apple Garamond. Apple adopted it in 1984 with the introduction of the Macintosh, and continued using it through the early years of the Aqua/iMac aesthetic. For me it evokes the pinnacle of the six-color era. For Apple’s brand identity and marketing materials, after Apple Garamond came Myriad — which Apple commissioned custom variants of from Adobe. And then Myriad was succeeded by San Francisco, which I suspect still has many years ahead of it. For the last 40 years Apple has only gone through three identity fonts: Garamond → Myriad → San Francisco.

That this style of font is back in vogue is fun. It’s a good look. Friendly. Serious but not staid. The typeface a lot of these brands are using for this today is Instrument Serif, which I don’t love. It’s not bad. But it’s not great. Apple Garamond was great.

(ITC Garamond — but not condensed — served, distinctively, as both the display and body text typeface for O’Reilly books in their heyday. That typeface doesn’t look or feel Apple-like at all, nor does Apple Garamond look or feel O’Reilly-like at all.)

Lawler: Another Strange NAR Reading on Northeast Median Sales Prices

Today, in the CalculatedRisk Real Estate Newsletter: Lawler: Another Strange NAR Reading on Northeast Median Sales Prices

Excerpt:
While today’s existing homes sales report from the National Association of Realtors didn’t contain many surprises, an exception was in the reported median existing home sales prices. The NAR report showed that the median existing home sales price (total and single-family) in November was up just 1.2% from a year earlier, well below both consensus and what local realtor/MLS data would have suggested. The source of this surprise was in the Northeast, where the NAR’s median existing home sales price estimate was up just 1.1% from last November, and the median existing single-family home sales price estimate was up only 0.9% YOY.

Apple Is Adding More Ad Spots to App Store Results

Apple, on its Apple Ads site:

Search is the way most people find and download apps on the App Store, with nearly 65 percent of downloads happening directly after a search. To help give advertisers more opportunities to drive downloads from search results, Apple Ads will introduce additional ads across search queries. You don’t need to change your campaign in order to be eligible for any new positions. Your ad will run in either the existing position — at the top of search results — or further down in search results. If you have a search results campaign running, your ad will be automatically eligible for all available positions, but you can’t select or bid for a particular one.

The ad format will be the same in any position, using a default product page or custom product page, and an optional deep link. You’ll be billed as usual based on your pricing model: cost per tap or cost per install.

I have a bad feeling about this.

ByteDance Signs Deal to Divest U.S. TikTok App

David Shepardson, reporting for Reuters:

TikTok’s Chinese owner, ByteDance, said Thursday it signed binding agreements with three major investors to form a joint venture to operate TikTok’s U.S. app led by American and global investors in a bid to avoid a U.S. government ban, a significant step toward ending years of uncertainty.

The craziest aspect of this whole saga is that TikTok has been operating illegally since Trump took office. Not some sort of nitpicking technicality. The whole point of the PAFACA act was to ban TikTok in the US until and unless they were sold to American owners. No cloud service. No app store downloads. Trump directed the Justice Department simply not to enforce the law … and the biggest companies in the world just said OK, sure.

This just isn’t normal. There are always edge cases in the enforcement of any law. Political leanings affect priorities. Old laws are often ignored. But PAFACA was a brand new law, with bipartisan support, specifically written to target TikTok, and the Trump administration decided to just ignore it. This wouldn’t happen anywhere in Europe or in, say, Japan. And it wouldn’t have happened under any previous US administration, Democrat or Republican. It’s not the biggest issue or worst wrongdoing of the Trump 2.0 administration, but it’s clearest indication of their disregard for the rule of law.

Michael Bierut Told Us What He Really Thinks of ITC Garamond

Michael Bierut, “I Hate ITC Garamond”, for Design Observer back in 2004:

ITC Garamond was designed in 1975 by Tony Stan for the International Typeface Corporation. Okay, let’s stop right there. I’ll admit it: the single phrase “designed in 1975 by Tony Stan” conjures up a entire world for me, a world of leisure suits, harvest gold refrigerators, and “Fly, Robin, Fly” by Silver Convention on the eight-track. A world where font designers were called “Tony” instead of “Tobias” or “Zuzana.” Is that the trouble with ITC Garamond? That it’s dated?

Maybe. Typefaces seem to live in the world differently than other designed objects. Take architecture, for example. As Paul Goldberger writes in his new book on the rebuilding of lower Manhattan, Up From Zero, “There are many phases to the relationships we have with buildings, and almost invariably they come around to acceptance.” Typefaces, on the other hand, seem to work the other way: they are enthusiastically embraced on arrival, and then they wear out their welcome. Yet there are fonts from the disco era that have been successively revived by new generations. Think of Pump, Aachen, or even Tony Stan’s own American Typewriter. But not ITC Garamond.

The most distinctive element of the typeface is its enormous lower-case x-height. In theory this improves its legibility, but only in the same way that dog poop’s creamy consistency in theory should make it more edible.

I can’t explain how it is that I’ve never linked to this piece before.

Adobe Photoshop 1.0 Source Code

The Computer History Museum:

Thomas Knoll, a PhD student in computer vision at the University of Michigan, had written a program in 1987 to display and modify digital images. His brother John, working at the movie visual effects company Industrial Light & Magic, found it useful for editing photos, but it wasn’t intended to be a product. Thomas said, “We developed it originally for our own personal use … it was a lot a fun to do.”

Gradually the program, called “Display”, became more sophisticated. In the summer of 1988 they realized that it indeed could be a credible commercial product. They renamed it “Photoshop” and began to search for a company to distribute it. About 200 copies of version 0.87 were bundled by slide scanner manufacturer Barneyscan as “Barneyscan XP”.

The fate of Photoshop was sealed when Adobe, encouraged by its art director Russell Brown, decided to buy a license to distribute an enhanced version of Photoshop. The deal was finalized in April 1989, and version 1.0 started shipping early in 1990.

Along with the 1.0 source code (mostly Pascal, with some 68K assembler), CHM has PDFs of Adobe’s excellent Photoshop 1.0 User Guide and Tutorial. CHM trustee Grady Booch, chief scientist for software engineering at IBM Research Almaden, on the source code:

There are only a few comments in the version 1.0 source code, most of which are associated with assembly language snippets. That said, the lack of comments is simply not an issue. This code is so literate, so easy to read, that comments might even have gotten in the way. [...] This is the kind of code I aspire to write.

A little birdie who works at Adobe today told me, regarding the lack of comments, “Let me assure you, that trend continued for the next 35 years.”

Jason Snell, at Six Colors, notes:

The only shame is that this release doesn’t include the code from the MacApp applications library, which Photoshop used and is owned by Apple. It would sure be nice if Apple made that code available as well.

Says my little birdie, “Turns out Adobe got a perpetual license to MacApp and a heavily modified version of it is still the basis of the UI code. It is only recently starting to get replaced. Even more crazy is that parts of that MacApp code are running on iOS and Android and the web versions.”

Quite the legacy for what started as a personal project between two brothers.

Still No Release Date for Apple TV’s ‘The Savant’

Apple TV’s press page has stories this month announcing release dates and first looks for a bunch of shows: Imperfect Women (a “psychological thriller”), Beat the Reaper (“dreamed”), a still-untitled Monarch: Legacy of Monsters spinoff, Widow’s Bay (“blends genuine horror with character-driven comedy”), season 2 of the Idris Elba thriller Hijack, and Margo’s Got Money Troubles, a series from David E. Kelley starring Elle Fanning, Michelle Pfeiffer, Nicole Kidman, and Nick Offerman (good cast!).

But not a word about Jessica Chastain’s The Savant, which was supposed to debut in September, was postponed after the Charlie Kirk shooting (against Chastain’s wishes), and has been in “At a later date” scheduling limbo ever since.

Anonymous Reddit Tipster Cracked the Brown University and MIT Shooting Cases

Alexander Smith and Claire Cardona, NBC News:

Online tipsters have had a mixed record when it comes to providing information about mass casualty incidents. But Rhode Island Attorney General Peter Neronha said this Reddit user “blew the case wide open” after posting about their encounter on Saturday with the suspect.

“I’m being dead serious,” wrote the Reddit user, identified in an affidavit as “John,” three days after the shootings at Brown. “The police need to look into a grey Nissan with Florida plates, possibly a rental.”

Apple Changes Processor Architectures More Often Than Its Identity Font

Yesterday I wrote:

For the last 40 years Apple has only gone through three identity fonts: Garamond → Myriad → San Francisco.

DF reader Cameron McKay emailed to observe: “It strikes me that Apple changes CPU architectures (68K → PowerPC → Intel → ARM) more often than identity fonts. They’d sooner re-engineer their products’ deepest technical building blocks than change typefaces. I suspect that’s rare among tech companies.”

I wish I’d thought to mention that yesterday.

I’ll add that I suspect San Francisco might effectively be Apple’s “forever font”. Forever is a long time, but San Francisco, in its default appearance, strives for the sort of timelessness that Helvetica achieved. And San Francisco offers a wide (no pun intended) variety of widths and weights. This is San Francisco. This is too. (Screenshots for posterity, when Apple’s website changes: iPhone 17 Pro and iPhone Air.)

I also suspect that Apple Silicon is Apple’s “forever architecture”.

★ A Request Regarding ‘Magic Link’ Sign-Ins and Apple’s Passwords App

In Juli Clover’s aforelinked rundown of what’s new across the whole system in iOS 26.2, I misunderstood this item regarding the Passwords app:

In the Settings section of the Passwords app, there’s an option to manage websites where passwords are not saved when signing in.

This new setting is about managing sites that you have previously excluded from having a password entry saved. (In the Settings app, go to Apps → Passwords and then tap “Show Excluded Websites”.)

What I was hoping this was about is a feature Passwords doesn’t have, but that I want. There are many sites — and the trend seems to be accelerating — that do not use passwords (or passkeys) for signing in. Instead, they only support signing in via expiring “magic links” sent by email (or, sometimes, via text messages). To sign in with such a site, you enter your email address, hit a button, and the site emails you a fresh link that you need to follow to sign in.1 I despise this design pattern, because it’s inherently slower than signing in using an email/password combination that was saved to my passwords app and autofilled by my web browser. My password manager is Apple Passwords and my browser is Safari, but this is true for any good password manager and web browser. It’s not just a little slower but a lot slower to sign in with a “magic link”. It sometimes takes minutes for the email to arrive, and even in the best case, it takes at least 15 seconds or so. Saved-password autofill, on the other hand, happens instantly.2

To make matters worse, when you create a new account using a “magic link”, nothing gets saved to Apple Passwords. I don’t have many email addresses in active use, but I do have several. Sometimes I don’t remember which one I used for my account on a certain site. It doesn’t get autofilled by Apple Passwords because account entries in Apple Passwords require a password. I was hoping the above feature mentioned by Clover was a way to address this — that you could now enable a setting to get Passwords to save just your email address for websites and services that exclusively use “magic links” for signing in. No dice. Apple Passwords team, if you’re reading this, please give this some thought. I can’t be the only person irritated by this.

One workaround I’ve used for a few sites with which I keep running into this situation (Status, I’m looking in your direction) is to manually create an entry in Apple Passwords for the site with the email address I used to subscribe, and a made-up single-character password. Apple Passwords won’t let you save an entry without something in the password field, and a single-character password is a visual clue to my future self why I did this. When I do this, I also put a note to myself in the notes field for the entry. And by using just a single character for the made-up password, I can tell what I did even when the password is displayed using bullets to obscure its actual characters. (Screenshot.) If you feel like I do about “magic links”, the 🖕 emoji is a good “password” for such entries.

Once saved like this, my email address still doesn’t autofill on such sites in Safari, but the list of my saved email addresses in the suggestion list that appears when I click in the Email text field will have a “saved password” label next to the one for which I made this entry in Apple Passwords. This at least solves the problem when I can’t remember which address I used to create my account on a site.

Better would be a way for Passwords to ask if you want to save just your email address for sites with “magic link” sign-ins, and then for Safari to autocomplete that address just like it does for username/password combinations. I can see how this would be a tricky problem for Apple Passwords to solve in a way that makes clear to the user why certain entries do not have passwords, but it’s a problem worth solving.


  1. This design pattern is common with paywalled subscription content sites, like email newsletters, to cut down on password sharing. Let’s say someone pays $10/month for a subscription-based newsletter. If they can sign in using an email/password combination, they might be willing to share their email/password combination for that particular site with a few friends or colleagues, to give them access to the same paywalled content without paying for their own subscriptions. Same goes for sharing email/password combinations for streaming services like Netflix. Well, you can’t share a password if there is no password to share. If the only way to log in to a subscription-based account is via a magic link that expires within minutes, it’s a lot harder for person A to share their account with person B (let alone with persons C, D, E, and F — nor can persons B through F share the account with others, because they don’t have access to the email). Person B has to tell person A that they’re signing in again, then person A has to wait for the email to arrive, and then person B needs to wait for person A to copy and paste the “magic” link, and hope it arrives before it expires. This pattern adds a significant convenience cost to account sharing — but it also makes signing in more annoying for honest users who aren’t sharing their accounts. ↩︎

  2. Proponents of “magic links” argue that they’re beneficial for technically befuddled users who don’t use a password manager. That’s a good argument for offering “magic links” as an option, but it’s not a good argument for making them the exclusive way to sign in to a site or service. Good password managers are built into modern OSes and web browsers. Those of us who use them should not be punished with a significantly worse experience just because some users do not. When “magic links” are offered as an alternative to a saved password or passkey, there’s a path for all users. When “magic links” are the exclusive method for signing in, all users get the slowest experience.

    (And yes, Passport, the subscription system behind Dithering and the rest of Ben Thompson’s Stratechery media empire, exclusively uses “magic links” for sign-in. I don’t like it, but, in Passports’s defense, once you’re signed in, Passport keeps you signed in for a very long time. Other CMSes tend to expire sign-ins far too quickly, which makes for a particularly frustrating experience with “magic links” because you need to keep using them every few weeks.) ↩︎︎

Apple’s 26.2 OS Updates

Apple released all of its OS 26.2 updates a week ago today. A little unusual for Apple to release OS updates on a Friday, but I think they wanted to get these out before Christmas week. And I don’t think it was rushed — for iOS 26.2 at least, there were two release candidate builds during beta testing. I suspect Apple had hoped to release them earlier.

I know it seemed weird back at WWDC when Apple announced that they were re-numbering all their OS versions to start with 26. But now that the change has settled in for a few months, it seems very natural. It’s so easy now to remember that the current major version for each OS is 26. It’s also easier to talk about new features that span across OSes. And, in the future, when you see a reference to, say, iOS 26, you’ll know exactly when that version came out without having to think, because it’s right there in the version number itself.

A few other notes:

Lastly, iOS 26.2 seems to be the release that Apple is starting to suggest as an upgrade for users who hadn’t already installed it by choice. Be prepared for questions and complaints from non-nerd friends and family who’ve never even heard of “Liquid Glass”.

Trump in Winter … Drift, Fragmentation and Just Low Energy

I’ve been under the weather. That partly explains missing two days of posts. But another reason is a feeling of repetition. Everything I see in our politics right now — or at least at the pinnacle where Donald Trump dominates all the visuals and attention — has a feeling of drift, spectacle and fragmentation. Trump’s ballroom epitomizes it — crass, stupid, vulgar, unacceptable and yet ultimately meaningless. It’s the full-size version of having his stacked Kennedy Center board, of which he is the chairman, rename the institution after him. That was, I believe, Wednesday, though the days run together. Then there’s his new hall of presidents, a sick-burn tweet storm embedded on a wall of what remains of the White House. These all have the feeling of a man who is bored, tapped out, losing coherence and energy and who others are trying to keep distracted.

The economy continues to reel and lurch under a weight-vest of tariffs and trade wars. Immigrants and brown people of all sorts are still menaced by ICE. The innocent are harassed; the guilty are pardoned. Alleged drug runners, but perhaps mere fishermen and boaters, are blown out of the water from a distance by U.S. Navy drones. All of it continues, and the country remains in the throes of a battle for the survival of civic democracy. In many ways, the predation remains at its highest point — because much of it has happened, has been consolidated, and people now react on the basis of those things having happened. Indeed, we may now be careening toward a war with Venezuela because one of Stephen Miller’s fiendish gambits directed at Mexico has metastasized in the general chaos into a regime change war against Venezuela.

What is uncanny about this though is that it’s incomplete and in key ways faltering. It’s also terribly unpopular. I cannot think of a single facet of the Trumpism of Practice circa 2025 that has not been rejected by the public at large. Many have been decisively, by overwhelming majorities. And yet there is neither any effort to bring these policies even somewhat into line with public opinion, even center-right public opinion, or move aggressively to take the steps that would make public opinion less immediately relevant. On the contrary, we see the administration taking all these actions that one would expect if Trump had fully consolidated control over the state’s so-called “power ministries” and secured full or fullish control over the state, eliminated real sources of opposition power and so forth. Only he hasn’t.

You might be saying, well, that’s what you think, Josh. He’s already done X, Y and Z. But it is what I think. And I’m pretty sure I’m right.

I’m not saying he’s toast or that everything is going to be fine. But he’s far from effectively locking everything down. And yet we’re rolling at full speed into what we what we might call North Korean aesthetics of power with triumphal arches that will soon enough be dusty, half-broken relics, renaming everything after the Maximum Leader. It’s all weird. And it is all of this very particular moment. In a way, the Susie Wiles drama is part of it. The person at the center of the White House power structure talked openly and disparagingly about the president. And the immediate reaction was for Wiles to issue what can only be called an intentionally absurd denial and for every Cabinet secretary to tweet out a post-struggle session-like emphatic defense of Wiles and pledge of fealty to Trump. In fact, by the end of the day Trump said in response to a question about Wiles that he agreed with what she said.

This is all deeply weird. But I think it tends to confirm everything I said above, as I noted in the post earlier this week about Wiles. It’s a sign of her power; it is a sign of the government’s weakness and unpopularity. (You don’t say the president is a weirdo who’s done a bunch of terrible things if everyone thinks things are awesome and the present is the future.) Finally, it is a sign of an emerging vacuum at the top — at the top of Trump’s body in his head, and at the top of the government in Trump. I’m not saying Trump is sick or dying or declining in cognitive terms. Those things are very possible. He may simply be bored and in need of distractions, which is of a piece with the sense enervation and fragmentation.

*Central Asia*, by Adeeb Khalid

An excellent book, the best I know of on this region.  Here is one bit:

The first printing press in Central Asia was established in Tashkent in 1870…

I had not understood how much Xinjiang (“East Turkestan”), prior to its absorption into newly communist China, fell under the sway of Soviet influence.

I had not known how much the central Asian republics had explicit “let’s slow down rural migration into the cities” policies during Soviet times.

The book is interesting throughout, recommended.

Young stars blow bubbles?

We know that a star’s childhood is turbulent: growing via a disc of gas and dust, the same disc from which planets form. Young stars also experience outbursts, expelling material via fast jets that regulate how much material is left to feed the young stars and form planets around it. Today’s Picture of the Week shows one of those jets interacting with the surrounding material. 

The background image, taken with the NASA/ESA Hubble Space Telescope, shows the young star SVS 13, located in the star-forming region NGC 1333 about 1000 light-years away. This star is expelling gas in the form of clumps known as “molecular bullets”. The insets show observations of one of those “bullets” taken with the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner. Each frame displays gas moving at different speeds, ranging from 35 km/s (red) to 97 km/s (blue).

This series of images is similar to a medical tomography, and allows astronomers to reconstruct the 3D shape of the rings and shells of gas that the jet creates as it interacts with its environment. “This is the first time such a degree of fine detail has been reached, thanks to the exquisite sensitivity achieved in our study with ALMA,” said Guillermo Blazquez-Calero, lead author of the study recently published in Nature Astronomy. This will help astronomers understand the not-so-peaceful infancy of stars and how planets form around them.

Agent Skills

Agent Skills

Anthropic have turned their skills mechanism into an "open standard", which I guess means it lives in an independent agentskills/agentskills GitHub repository now? I wouldn't be surprised to see this end up in the AAIF, recently the new home of the MCP specification.

The specification itself lives at agentskills.io/specification, published from docs/specification.mdx in the repo.

It is a deliciously tiny specification - you can read the entire thing in just a few minutes. It's also quite heavily under-specified - for example, there's a metadata field described like this:

Clients can use this to store additional properties not defined by the Agent Skills spec

We recommend making your key names reasonably unique to avoid accidental conflicts

And an allowed-skills field:

Experimental. Support for this field may vary between agent implementations

Example:

allowed-tools: Bash(git:*) Bash(jq:*) Read

The Agent Skills homepage promotes adoption by OpenCode, Cursor,Amp, Letta, goose, GitHub, and VS Code. Notably absent is OpenAI, who are quietly tinkering with skills but don't appear to have formally announced their support just yet.

Update 20th December 2025: OpenAI have added Skills to the Codex documentation and the Codex logo is now featured on the Agent Skills homepage (as of this commit.)

Trump Gets Ready to Get His War On

The U.S.S Gerald Ford off St. Thomas, U.S. Virgin Islands, as part of the Trump administration’s military deployments aimed at Venezuela (photo by U.S. Navy)

The Cross Section is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.

Donald Trump has had some pretty dumb ideas in his long and eventful political life, but invading Venezuela has to be among the dumbest.

It may seem unlikely that he’ll actually mount a full-scale ground invasion, but Trump has grown so addled that it’s impossible to say with certainty that there’s anything he won’t do. His current position is “I don’t rule it out,” and if his approval ratings continue their downward slide, it wouldn’t be hard to see him warming to the idea that a fun little war could be just what the doctor ordered to restore the vim and vigor he has been lacking.

But would the public actually allow it? Trump may be less concerned about public sentiment than most presidents, but even he is constrained by what the people will agree to. And no public on earth has had to consider whether they want their government to go to war more often than we have. Whenever we face this question, we view it through the lens of the last war, and there’s always one that ended within recent memory. Because America never goes too long without invading somebody or other.

Judging by their words and actions, it would certainly seem like the administration is preparing for war. We’re bombing boats in Venezuelan waters left and right. We’ve now moved significant military resources nearby, and blockaded the country. We’re seizing its oil tankers. CNN counted 17 times in recent months that Trump has said some kind of strike on Venezuelan land could happen “soon.” Trump shouted on Truth Social that “the Venezuelan Regime has been designated a FOREIGN TERRORIST ORGANIZATION,” which is incoherent but is clearly meant to portray Venezuela as an imminent threat to your very life. And his administration recently declared “a new ‘Trump Corollary’ to the Monroe Doctrine,” the 19th century assertion of US sovereignty over every country in the hemisphere, which began our long history of invasions, coups, and interventions into almost every country in South and Central America.

If he does make a decision to invade, Trump will have plenty of support from the Republican Party and all its auxiliary institutions, and not just because they line up behind him in whatever absurd thing he proposes. They may not have thought about getting back in the war biz for a while, but as soon as it began to look like a real possibility they’d barely be able to contain their excitement.

I wouldn’t be surprised if Secretary of Defense Hegseth is already lobbying Trump to go big, to get beyond bombing boats supposedly carrying drugs to something much more thrillingly kinetic (Hegseth names every new action “Operation Pounding Hammer” or some such, as though he wanted to call it “Operation I Don’t Have A Small Penis, YOU Have A Small Penis” but decided not to be so obvious). Trump’s hawkish supporters in Congress would line up to cheer; I think I can hear Lindsey Graham giggling in anticipation. The right-wing groups like the Heritage Foundation would mobilize their senior fellows and email blasts to pound the drums.

And the powerful octopus that is the right-wing media, stronger than it has ever been, would be on board too. You think Fox News wouldn’t be psyched beyond belief for a full-on war? Oh my goodness — the graphics, the music, the immersive VR stage sets! It’s gonna rock!

Remembering and forgetting Iraq

I wish I could say that the public at large would never get behind such a thing, and the lack of support will inevitably stay Trump’s hand. But while that’s possible, I don’t think it’s guaranteed. Because what ought to be the fundamental lessons of our history and the world’s history — things like “Wars are terrible and should be avoided at all cost,” or “It’s foolish to think that even people suffering under dictators want us to come in, kill a bunch of them, and lay waste to their country” or “If you think this is going to be easy, you’re almost certainly wrong” — never seem to be learned, at least by enough people for a long enough period.

The recent history that got us to where we are now really starts in the first Gulf War in 1991, which itself took place in the shadow of the Vietnam War, which ended sixteen years before. Vietnam had been called “the living room war” because it was the first one where footage of battles was shown regularly on TV news. But the Gulf War I was truly the first televised war, as the Pentagon deployed a complex and carefully planned media strategy to go along with its war strategy.

That involved convincing Americans that the whole thing was essentially bloodless, not just in terms of American casualties but among Iraqis too (which was far from true; tens of thousands of Iraqi civilians and soldiers died). Here’s a remarkable moment, when Gen. Norman Schwarzkopf, the commander of the operation, showed a video of “the luckiest man in Iraq,” a video of a car crossing a bridge just before an American bomb destroyed it. All the reporters in the room laughed:

After the end of that war, George H. W. Bush said triumphantly, “By god, we’ve kicked the Vietnam syndrome once and for all.” The “syndrome” to which he referred wasn’t so much about military failure but the public’s reluctance to support invasions of foreign countries. Here’s an article from the Los Angeles Times published the next day:

War was fun again! What a relief.

Let’s jump ahead to 2002, when the administration of the lesser Bush began preparing the ground for an even bigger war against Iraq. The fact that we were still living in the aftermath of 9/11 meant that Americans still had both a sense of vulnerability and a desire for revenge, and neither had been satisfied by the Afghanistan War, which had already become a slog. So when the Bush administration told America that Saddam Hussein probably had something to do with 9/11 and he possessed a fearsome arsenal he would inevitably use to kill your children — in the words of Dick Cheney, “There is no doubt that Saddam Hussein now has weapons of mass destruction. There is no doubt he is amassing them to use against our friends, against our allies, and against us” — the people were ready to be persuaded.

There were plenty of us who raised our voices in objection. But we were dismissed as anti-American and pro-terrorist, or just weak, naïve, and cowardly. When it began, the war had the support of about two-thirds of the public, including most of the Democratic establishment — who really were weak and cowardly, since they almost certainly knew what a mistake it was, and that the administration was lying about almost everything. But they didn’t have the courage to say no.

There was also a pervasive sense of excitement when the Iraq War started. People thought it was going to be awesome — we’d march in there, get rid of a dictator, the Iraqi people would greet us with flowers and candy (“We will, in fact, be greeted as liberators,” Cheney said), and then a wave of democracy would spread across the Middle East. Vietnam had been superseded in the public’s mind by the Gulf War and 9/11, and the warnings by almost everyone who knew anything about the Middle East were swept aside.

This is not 2003

That brings us to today. The utter catastrophe that Iraq became (and to a lesser extent Afghanistan) is still the lens through which the public is going to view the possibility of war with Venezuela. Nobody is referring to an “Iraq syndrome” in public opinion, but that’s what it is. A CBS poll taken last month showed that 70% of respondents opposed military action against Venezuela, and a more recent one from Quinnipiac showed opposition at 63% - 25%.

We also have to remember that the Trump team has none of the propaganda skills the Bush administration did. On an individual level, most of them are just pretty dumb, and collectively they fashion themselves into a reflection of Trump’s own personality and impulses, which prevents them from persuading anyone who isn’t already on their side. Nor is Trump himself much good as a communicator these days; while he has certainly long been a charismatic presence, he never had a great ability to convince large numbers of people of something they didn’t already believe, and what skills he had are rapidly deteriorating. And they still can’t settle on a justification to what is clearly an effort to overthrow the government of Nicolás Maduro — sometimes it’s because of fentanyl (which isn’t made in Venezuela), sometimes it’s because they took our oil (I kid you not), and sometimes it’s because Maduro is a bad guy (true but barely relevant). None of those is particularly compelling as a justification for war.

But as I’ve been thinking about this, there’s something I can’t get out of my head. World War II was far and away the most monumental horror ever experienced by the human race; while there are varying estimates of the death toll, 50 million or so is the low end, depending on what you include. With it came some of the most gruesome events anyone had ever even learned about, let alone experienced — the killing of tens or even hundreds of thousands in a single night in places like Tokyo and Dresden; the Bataan Death March; at least a million dead and likely many more at the Battle of Stalingrad; the twin explosions of the deadliest weapons ever devised; and of course the Holocaust, a combination of mechanized mass slaughter and widely distributed savagery from both military and civilians that should have been enough to make anyone question whether a species capable of such things was even deserving of survival.

One would think that out of that experience, it would be decades at least before any public reacted to even the suggestion of beginning or joining a new war with anything other than terror and universal political resistance. And yet, just five years after World War II ended, Americans were told “Hey folks, we’re going to go do another land war in Asia,” and their response was “Okay, I guess.” I’m not trying to make any particular argument about the Korean war; my point is just that it’s striking that the public wasn’t more opposed (public opinion on Korea was divided, but there was never anything like widespread rejection of U.S. involvement in the war).

That was a long time ago, but one of the lessons, I think, is that whether our last war is considered a failure or a success matters more to whether we’re ready to have a new one than the actual cost of the war in human suffering. That’s especially true when it comes to the price paid by people who aren’t American.

So yes, for now the public is not at all eager to launch a new war in Venezuela, especially since it’s an extremely unpopular president who wants to start it. But if this isn’t our next war, there will be another one sooner or later. And another one after that.

Lies, Damned Lies and Trump Speeches

Source

Today is a travel day so this will be a short post. Fortunately the main topic that I want to talk about is uncomplicated – the speech that Donald Trump gave on Wednesday night. The purpose of the speech was to turn around Trump’s cratering public approval on his handling of the economy. I will also address a slightly more complicated topic: health insurance and the complete inability of Trump and Republicans in general to address public concerns about healthcare affordability.

To paraphrase Thomas Hobbes, Trump’s speech was nasty, brutish, but, mercifully, short. Apparently it was short because the networks told him that they would only give him 15 minutes (although they didn’t cut away when he went over). It was a blizzard of lies. I can’t find a single factual assertion Trump made that was true.

So many lies, so little time, as well as reader patience. However, the major media organizations are doing a decent job of fact-checking, so I won’t inflict upon you another laundry list of his mendacities.

Yet one hallucination I will highlight — in this case I say “hallucination” rather than lie because Trump, surrounded by sycophants, may actually believe it — is his persistent claim that the world despised the US economy a year ago and now admires his achievements. From the speech:

One year ago, our country was dead. We were absolutely dead. Our country was ready to fail. Totally fail. Now we’re the hottest country anywhere in the world. And that’s said by every single leader that I’ve spoken to over the last five months.

What was the world actually saying about America a year ago? From The Economist, in October 2024:

A person on a unicycle with a flag in front of a crowd of people

AI-generated content may be incorrect.

Furthermore, truth wasn’t the only thing completely lacking in Trump’s diatribe. Also lacking was anything resembling an actual policy to deal with concerns about affordability.

It was notable that while making the false claim that overall prices are coming down, the specific prices Trump highlighted (with fake numbers) were turkeys, eggs and gasoline — all prices over which policy has very little influence. Egg prices, for example, fluctuate wildly over time, not because of anything the government does, but because of the vagaries of bird flu. And, by the way, the Trump Administration has shut down a research project that was developing a bird flu vaccine.

Healthcare, by contrast, is an area where policy has a huge effect on affordability. It’s also an area in which Trump talked utter nonsense.

Here’s what you should know: The Affordable Care Act, aka Obamacare, offers Americans who aren’t covered by Medicare, Medicaid or through their employers the ability to purchase insurance coverage from private insurers, with the federal government subsidizing most enrollees’ premiums. However, enhanced subsidies put in place under the Biden administration will expire on January 1st, 2026, leading to large cost increases for many families.

Costs will soar for two reasons. There’s the direct effect of losing subsidies. But there’s also an indirect effect, because the loss of subsidies will lead millions of people to drop their coverage — and those who drop coverage will, on average, be healthier than those who don’t, worsening the risk pool. Insurers, anticipating this effect, have already sharply raised premiums.

Charts from KFF show the effects on some representative couples. More than 20 million would be affected, but the worst hit will be older, moderately well-off Americans who are earning just a bit too much to remain eligible for subsidies. For example, a 60-year-old couple with an income of $85,000 will face a premium hike equal to more than a quarter of their pre-tax income:

What should the Trump Administration do? Here’s Trump:

I’m also taking on the gigantic health insurance companies that have gotten rich on billions of dollars of money that should go directly to the people. The money should go to the people. That’s you, so they can buy their own health insurance, which will give far better benefits at much lower costs.

So Trump says that he’ll replace the current system, in which people buy their own health insurance with the aid of government subsidies, with a system in which the government gives people money they can use to buy their own health insurance. How is that different?

In fact, it isn’t different except for one devastating detail: Republicans in Congress will never approve subsidies adequate to make health insurance affordable. Because the Republican plan would be far stingier than the one currently in place, millions of people will be forced to drop their insurance. And as I said, because it’s the younger and relatively more healthy that will drop their coverage, the pool of those who keep their coverage will be older and sicker. And you know what happens next – premiums go up even further. No wonder that four Republican congressmen in purple districts defied Mike Johnson and voted to extend the Obamacare subsidies.

So what should we make of Trump’s speech? Many commentators are describing it as a nothingburger, because it’s unlikely to do anything to move the political needle. (PS: The price of nothingburgers has risen 18 percent since Trump took office.)

Let me say something about the latest report on consumer prices, which showed lower inflation than expected. The general view among economists I follow is that this report was seriously distorted by the effects of the government shutdown, although we don’t know by how much. For now, the best guess is that troubling inflation, and with it public concern about affordability, will persist.

But leaving the short-run politics aside, the speech revealed something important: Namely, Trump has no idea how to govern. Faced with adversity, he’s unable to propose policies to improve the situation. All he can do iscontinue to gaslight the public and claim that everything is great, while smearing his opponents.

That was a short speech, but it presages a very long next three years for ordinary Americans. And for congressional Republicans, it presages a very ugly November 2026.

MUSICAL CODA

Introducing GPT-5.2-Codex

Introducing GPT-5.2-Codex

The latest in OpenAI's Codex family of models (not the same thing as their Codex CLI or Codex Cloud coding agent tools).

GPT‑5.2-Codex is a version of GPT‑5.2⁠ further optimized for agentic coding in Codex, including improvements on long-horizon work through context compaction, stronger performance on large code changes like refactors and migrations, improved performance in Windows environments, and significantly stronger cybersecurity capabilities.

As with some previous Codex models this one is available via their Codex coding agents now and will be coming to the API "in the coming weeks". Unlike previous models there's a new invite-only preview process for vetted cybersecurity professionals for "more permissive models".

I've been very impressed recently with GPT 5.2's ability to tackle multi-hour agentic coding challenges. 5.2 Codex scores 64% on the Terminal-Bench 2.0 benchmark that GPT-5.2 scored 62.2% on. I'm not sure how concrete that 1.8% improvement will be!

I didn't hack API access together this time (see previous attempts), instead opting to just ask Codex CLI to "Generate an SVG of a pelican riding a bicycle" while running the new model (effort medium). Here's the transcript in my new Codex CLI timeline viewer, and here's the pelican it drew:

Alt text by GPT-5.2-Codex: A minimalist illustration of a white pelican with a large orange beak riding a teal bicycle across a sandy strip of ground. The pelican leans forward as if pedaling, its wings tucked back and legs reaching toward the pedals. Simple gray motion lines trail behind it, and a pale yellow sun sits in the top‑right against a warm beige sky.

Filtered for conspiracy theories

1.

Why Were All the Bells in the World Removed? The Forgotten Power of Sound and Frequency (Jamie Freeman).

Church bells: "something strange happened in the 19th and 20th centuries: nearly all of the world’s ancient bells were removed, melted down, or destroyed."

(I don’t know whether that’s true, but go with it for a second.)

Why? Mainstream historians attribute this mass removal to wars and the need for metal, but when you dig deeper, the story doesn’t add up.

An explanation:

Some theorists believe that these bells were part of a Tartarian energy grid, designed to harmonise human consciousness, balance electromagnetic fields, and even generate free energy. Removing the bells would have disrupted this energy network, cutting us off from an ancient technology we no longer understand.

Tartarian?

Tartarian Empire (Wikipedia):

Tartary, or Tartaria, is a historical name for Central Asia and Siberia. Conspiracy theories assert that Tartary, or the Tartarian Empire, was a lost civilization with advanced technology and culture.

2.

Risky Wealth: Would You Dare to Open the Mysterious Sealed Door of Padmanabhaswamy Temple? (Ancient Origins).

"The Padmanabhaswamy Temple is a Hindu temple situated in Thiruvananthapuram, Kerala, a province on the southwestern coast of India."

It has a mysterious Vault B with an as-yet-unopened sealed door.

One of the legends surrounding Vault B is that it is impossible at present to open its door. It has been claimed that the door of the vault is magically sealed by sound waves from a secret chant that is now lost. In addition, it is claimed that only a holy man with the knowledge of this chant would be capable of opening the vault’s door.

Maybe the chant was intended to tap Tartarian energies.

3.

Claims that former US military project is being used to manipulate the weather are “nonsense” (RMIT University).

HAARP is a US research program that uses radio waves to study the ionosphere (Earth’s upper atmosphere) and cannot manipulate weather systems.

PREVIOUSLY:

Artificial weather as a military technology (2020), discussing a 1996 study from the US military, "Weather as a Force Multiplier: Owning the Weather in 2025."

4.

What conspiracy theorists get right (Reasonable People #42, Tom Stafford).

Stafford lists 4 “epistemic virtues” of conspiracy theorists:

  • "Listening to other people"
  • "A healthy skepticism towards state power"
  • "Being sensitive to hidden coalitions"
  • "Willing to believe the absurd"

As traits in a search for new truths, these are good qualities!

Where is goes wrong is "the vices of conspiracy theory seem only to be the virtues carried to excess."

Let’s try to keep the right side of the line folks.

Newsletter: NAR: Existing-Home Sales Increased to 4.13 million SAAR in November

Today, in the CalculatedRisk Real Estate Newsletter: NAR: Existing-Home Sales Increased to 4.13 million SAAR in November

Excerpt:
The fourth graph shows existing home sales by month for 2024 and 2025.

Existing Home Sales Year-over-yearSales were down 1.0% year-over-year compared to November 2024. The last month of 2025 will have a difficult year-over-year comparison.
...
Year-to-date, sales are down 0.5% compared to last year - and 2024 was the lowest level of sales since 1995! Sales this year will be close to last year.

Will this be the lowest level of sales in 30 years? Maybe. But there was one more working day in December this year compared to last year, so sales in 2025 might beat 2024.
There is much more in the article.

NAR: Existing-Home Sales Increased to 4.13 million SAAR in November

From the NAR: NAR Existing-Home Sales Report Shows 0.5% Increase in November
Month-over-month

• 0.5% increase in existing-home sales – seasonally adjusted annual rate of 4.13 million in November

• 5.9% decrease in unsold inventory – 1.43 million units equal to 4.2 months' supply

Year-over-year

• 1.0% decrease in existing-home sales

• 1.2% increase in median existing-home sales price to $409,200
emphasis added
Existing Home SalesClick on graph for larger image.

This graph shows existing home sales, on a Seasonally Adjusted Annual Rate (SAAR) basis since 1994.

Sales in November (4.13 million SAAR) were up 0.5% from the previous month and were down 1.0% compared to the November 2024 sales rate.  

The second graph shows nationwide inventory for existing homes.

Existing Home InventoryAccording to the NAR, inventory decreased to 1.43 million in November from 1.52 million the previous month.

Headline inventory is not seasonally adjusted, and inventory usually decreases to the seasonal lows in December and January, and peaks in mid-to-late summer.

The last graph shows the year-over-year (YoY) change in reported existing home inventory and months-of-supply. Since inventory is not seasonally adjusted, it really helps to look at the YoY change. Note: Months-of-supply is based on the seasonally adjusted sales and not seasonally adjusted inventory.

Year-over-year Inventory Inventory was up 7.5% year-over-year (blue) in November compared to November 2024.

Months of supply (red) decreased to 4.2 months in November from 4.4 months the previous month.

I'll have more later. 

AI Advertising Company Hacked

At least some of this is coming to light:

Doublespeed, a startup backed by Andreessen Horowitz (a16z) that uses a phone farm to manage at least hundreds of AI-generated social media accounts and promote products has been hacked. The hack reveals what products the AI-generated accounts are promoting, often without the required disclosure that these are advertisements, and allowed the hacker to take control of more than 1,000 smartphones that power the company.

The hacker, who asked for anonymity because he feared retaliation from the company, said he reported the vulnerability to Doublespeed on October 31. At the time of writing, the hacker said he still has access to the company’s backend, including the phone farm itself.

Hotels: Occupancy Rate Decreased 1.6% Year-over-year

Hotel occupancy was weak over the summer months, due to less international tourism.  The fall months are mostly domestic travel and occupancy is still under pressure! 

From STR: U.S. hotel results for week ending 13 December
The U.S. hotel industry reported mixed year-over-year comparisons, according to CoStar’s latest data through 13 December. ...

7-13 December 2025 (percentage change from comparable week in 2024):

Occupancy: 58.6% (-1.6%)
• Average daily rate (ADR): US$156.46 (+0.4%)
• Revenue per available room (RevPAR): US$91.76 (-1.1%)
emphasis added
The following graph shows the seasonal pattern for the hotel occupancy rate using the four-week average.

Hotel Occupancy RateClick on graph for larger image.

The red line is for 2025, blue is the median, and dashed light blue is for 2024.  Dashed black is for 2018, the record year for hotel occupancy. 

The 4-week average of the occupancy rate is tracking well behind last year but is close to the median rate for the period 2000 through 2024 (Blue).

Note: Y-axis doesn't start at zero to better show the seasonal change.

The 4-week average will decrease seasonally until early next year.

On a year-to-date basis, the only worse years for occupancy over the last 25 years were pandemic or recession years.

Navigating congested (dating) markets: Judd Kessler's advice for the frustrated

 Pessimistic about dating? Harvard-trained economist says do 2 simple things to improve your luck
by Judd B. Kessler

 1. Ditch the disinterested
Aggressively screen out people based on their interest in you.  

...

"2. Lean into idiosyncratic preferences
Identify what you — and specifically you — desire in a partner. What do you particularly value that may not be commonly desired by others? Economists call these your idiosyncratic preferences, distinguishing them from general preferences that are more commonly held. 

...

"And since people are looking for idiosyncrasies, you should advertise yours, too. Let potential daters know about your quirks (the kind that attract some people while repelling others) on your profile and on first dates. Sure it might send some people packing, but the ones who are drawn to you are better matches anyway.  

"A focus on idiosyncratic preferences can turn the “too many options” problem of dating apps back into a plus. A larger dating pool means there are probably more people out there who are quirky in the particular ways you like. To be successful in the dating market — during cuffing season or otherwise — you just have to make sure your energy is focused on finding them. "

These are the flying discs the government wants you to know about

Four small satellites rode a Rocket Lab Electron launch vehicle into orbit from Virginia early Thursday, beginning a government-funded technology demonstration mission to test the performance of a new spacecraft design.

The satellites were nestled inside a cylindrical dispenser on top of the 59-foot-tall (18-meter) Electron rocket when it lifted off from NASA’s Wallops Flight Facility at 12:03 am EST (05:03 UTC). A little more than an hour later, the rocket’s upper stage released the satellites one at a time at an altitude of about 340 miles (550 kilometers).

The launch was the starting gun for a proof-of-concept mission to test the viability of a new kind of satellite called DiskSats. These satellites were designed by the Aerospace Corporation, a nonprofit federally funded research and development center. The project is jointly financed by NASA and the US Space Force, which paid for DiskSat’s development and launch, respectively.

Nabeel on reading Proust

From Nabeel Qureshi:

Yet not a word is wasted. It sounds paradoxical, but Proust is economical with his prose. He is simply trying to describe things that are extremely fine-grained and high-dimensional, and that takes many words. He is trying to pin down things that have never been pinned down before. And it turns out you can, indeed, write 100 pages about the experience of falling asleep, and find all kinds of richness in that experience.

And this:

…, a clear-sightedness on human vanity and a total willingness to embarrass himself. There are passages in the Albertine sections which are shocking – such as the extended stretch, around 50 pages long, in which he describes watching her sleep — and, reading them, you start to understand that this was written by a dying man who did not care about anything apart from telling the whole truth in as merciless way as possible.

Third, hypotaxis in sentences. The opposite of hypotaxis is parataxis, which you often find in Hemingway, as in: “The rain stopped and the crowd went away and the square was empty.” Each item here is side by side, simple, clean. The Bible often uses such types of sentences: “And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness.”.

Hypotaxis, by contrast, describes sentences with many subordinate clauses, like nesting dolls.

Nabeel says In Search of Lost Time is now his favorite novel.
