What I’ve been reading

1. I have been reading in the history of archaeology, and have profited from Eric H. Cline, Three Stones Make a Wall: The Story of Archaeology, which is a very good introduction to what the subtitle claims.  There is also Toby Wilkinson, A World Beneath the Sands: The Golden Age of Egyptology, and Jason Thompson, Wonderful Things: A History of Egyptology, volume 2, The Golden Age: 1881-1914.

2. Elizabeth Alker, Everything We Do is Music: How 20th-Century Classical Music Shaped Pop.  A very good and readable book on this interaction, with excellent discussions of Donna Summer, Stevie Wonder, La Monte Young, and Penderecki, among many others.

3. Arindrajit Dube, The Wage Standard: What’s Wrong in the Labor Market and How to Fix It.  Dube notes his main theme is that employers have discretion in setting the real wage. A good overview of his work in labor economics.  I would stress that if you think “tight labor markets” are good for workers, you should be obsessed with doing lots to favor capital.

4. Richard H. Davis, Religions of Early India: A Cultural History.  A very useful background read for understanding later Indian history and religions, as well as the more general spread of religion throughout the southern regions of Asia.  Avoids the common mistake of becoming too obscure on these topics.

For those interested in the longer term, there is Hilary Greaves, Jacob Barrett, and David Thorstad, editors, Essays on Longtermism: Present Action for the Distant Future.

There is Kevin Kelly, Colors of Asia: A Visual Journey, Photos and Design.

Alvaro Rivas, Marx in the Age of AI: How Artificial Intelligence Reshapes Value, Class, and Ideology is a short but serious look as to how Marxian concepts might apply to AI, for instance whether surplus value will be earned on the AIs, or for that matter on non-human animals.

You will find a different intersection of topic areas in Dominic Roser, David Zhang, and J.D. Bauman, All the Lives You Can Change: Effective Altruism for Christians.

Ten Economic Questions for 2026

Monday:
• At 8:30 AM ET, Chicago Fed National Activity Index for November. This is a composite index of other data.

From CNBC: Pre-Market Data and Bloomberg futures S&P 500 are up 21 and DOW futures are up 100 (fair value).

Oil prices were down over the last week with WTI futures at $56.79 per barrel and Brent at $60.76 per barrel. A year ago, WTI was at $70, and Brent was at $73 - so WTI oil prices are down about 19% year-over-year.

Here is a graph from Gasbuddy.com for nationwide gasoline prices. Nationally prices are at $2.80 per gallon. A year ago, prices were at $3.01 per gallon, so gasoline prices are down $0.21 year-over-year.

After dinner I walked to my brother’s, where he told me some hopes he had of bringing his business to pass still of his mistress, but I do find they do stand upon terms that will not be either fit or in his power to grant, and therefore I did dislike his talk and advised him to give it quite over.

w/e 2025-12-21

The past few days I’ve been back in Essex, my sister and I continuing the task of sorting through every item accumulated in the family home over six decades.

An almost impossible quantity of things carefully preserved in every drawer, cupboard, box, filing cabinet, corner, nook and cranny. Some can be easily thrown away, some deserves finding a good home, some is heartbreakingly sentimental, and then lots of, “oh, hmm, what do we do with this?”

As usual I was slightly dreading coming here, backwards to all the memories, in order to be faced with so many tiny decisions over and over again. But within a day I, we, don’t want to leave. Everything is so familiar, so just right, so much part of us and our first half-centuries. How can it be that at some point we’ll no longer be able to sit in the same chairs in the same rooms and look at all these familiar things?

We’re dismantling lives. Wanting to go back to a couple of years ago. Wishing we could spend another Christmas here in this house where we grew up, in the town where Mum and Dad made their lives, rooting themselves into the history and politics of the place.

So many tears now because of so many happy memories.


§ Back home the builders have nearly finished the garage renovations after four weeks, with a brand new, non-leaking roof, OSB board on the inside walls, new lights and power sockets, and wood cladding on the outside.

The builders were lovely and we were able to be unknowledgably vague about our needs and leave it to them to decide the plan and do a good job. But it will be nice to not have builders around soon.


§ We watched The Mastermind (Kelly Reichardt, 2025) which was good but I maybe went into it expecting “heist” rather than “Kelly Reichardt” and so was a little disappointed when it didn’t follow a typical, increasingly tense, heist tale but instead decreasing amounts of things happened until it ended.


§ It is tiring, all the sorting. All the bending down, standing up, moving things around, and then the endless stream of decision-making, working out what to do with every individual sheet of paper, etc. But we’ve made visible progress. Still so much to do, for next time.

I might have a break from weeknotes next weekend. We’ll see. Have a good seasonal week or fortnight. Well done, we all made it.

Affordability, Part IV

Meet Jeff Bezos' fleet and its Lauren Sanchez figurehead | New York Post

On Friday the University of Michigan released its latest report on consumer sentiment, and it revealed deep dissatisfaction with the economy. The survey respondents rate current economic conditions as the worst in the past fifty years.

Source

As I documented in the first installment in this four-part series on affordability, the depth of this negativity far outstrips what standard measures of economic conditions tell us about the current state of the economy. In the second installment I examined various factors that may explain why Americans feel that their lives have become less affordable – factors, like the burden of higher interest rates, that are not captured in the standard measures. In the third installment I proposed a series of practical policy steps to improve general affordability – such as removing Trump’s tariffs and building more low-cost housing.

Yet, even when we go beyond the standard economic measures when assessing today’s economy, we are still unable to fully explain Americans’ extreme economic negativity. The economy of 2025 is still not worse than the economy of 2009, which was ravaged by the after-effects of the 2008 financial crisis. Neither is it worse than 1980, when the economy was suffering both high unemployment and double-digit inflation.

So in an effort to explain this conundrum, I will focus today’s installment, the last in the series, on three considerations that go beyond our standard interpretation of affordability. But, as I will argue, these three considerations significantly affect how people feel about the economy.

The first is inclusion: Do people feel able to afford goods and services that allow them to be full members of society? That is, do the feel able to live the American dream? The second is security: Even when people have reasonably high purchasing power, do they worry that they could easily fall off the edge? Finally, there’s fairness: Do Americans feel that the system is rigged against ordinary people like themselves?

Beyond the paywall I’ll examine each of these three issues. And in concluding, I will discuss how the public’s concerns about affordability can be the driver for real, and much needed, economic reform in America.

Quoting Shriram Krishnamurthi

Every time you are inclined to use the word “teach”, replace it with “learn”. That is, instead of saying, “I teach”, say “They learn”. It’s very easy to determine what you teach; you can just fill slides with text and claim to have taught. Shift your focus to determining how you know whether they learned what you claim to have taught (or indeed anything at all!). That is much harder, but that is also the real objective of any educator.

CSRF Protection without Tokens or Hidden Form Fields

A couple of months ago, I received a request from a random Internet user to add CSRF protection to my little web framework Microdot, and I thought it was a fantastic idea.

When I set off to do this work in early November I expected I was going to have to deal with anti-CSRF tokens, double-submit cookies and hidden form fields, pretty much the traditional elements that we have used to build a defense against CSRF for years. And I did start along this tedious route. But then I bumped into a new way some people are dealing with CSRF attacks that is way simpler, which I describe below.

Ten Economic Questions for 2026

Here is a review of the Ten Economic Questions for 2025.

Below are my ten questions for 2026 (I've been doing this online every year for 21 years!).  These are just questions; I'll follow up with some thoughts on each of these questions.

The purpose of these questions is to provide a framework of how the U.S. economy will likely perform in 2026, and if there are surprises - like in 2020 with the pandemic - to adjust my thinking.
  
1) Economic growth: Economic growth was probably close to 2% Q4-over-Q4 in 2025.  The FOMC is expecting growth of 2.1% to 2.5% Q4-over-Q4 in 2026. How much will the economy grow in 2026?  Will there be a recession in 2026?

2) Employment: Through November 2025, the economy added 610 thousand jobs in 2025.   How many jobs will be added in 2026?  Or will the economy lose jobs? 

3) Unemployment Rate: The unemployment rate was at 4.6% in November, up from 4.2% in November 2024.   Currently the FOMC is projecting the unemployment rate will decrease to the 4.3% to 4.4% range in Q4 2026.  What will the unemployment rate be in December 2026?

4) Participation Rate: In November 2025, the overall participation rate was at 62.5%, unchanged year-over-year from 62.5% in November 2024, and below the pre-pandemic level of 63.3% in February 2020.   Long term, the BLS is projecting the overall participation rate will decline to 61.1% by 2034 due to demographics.  What will the participation rate be in December 2026?

5) Inflation: Core PCE was up 2.8% YoY through September. This was down from a peak of 5.6% in early 2022.  The FOMC is forecasting the YoY change in core PCE will be in the 2.4% to 2.6% range in Q4 2025. Will the core inflation rate decrease further in 2026, and what will the YoY core inflation rate be in December 2026? 

6) Monetary Policy:  The FOMC cut the federal funds rate three times in 2025 from "4-1/4 to 4-1/2 percent" at the beginning of 2025, to "3-1/2 to 3-3/4" at the end of the year. The mid-point on the "dot plot" suggests many FOMC participants expect around two 25 bp rate cuts in 2026.  What will the Fed Funds rate be in December 2026?

7) Wage Growth: Wage growth was decemt in 2025, up 3.5% year-over-year as of November.  How much will wages increase in 2026?

8) Residential Investment: How much will Residential investment (RI)  change in 2026?  How about housing starts and new home sales in 2025?

9) House Prices: It appears house prices - as measured by the national repeat sales index (Case-Shiller, FHFA, and Freddie Mac) - will be mostly flat in 2025.  What will happen with house prices in 2026?

10) Housing Inventory: Housing inventory decreased sharply during the pandemic to record lows in early 2022.  Since then, inventory has increased but is still below pre-pandemic levels.  Will inventory increase further in 2026?

Michel Callon (1945–2025): A life with passion for economies, in J. of Cultural Economy

Here's an appreciation of the great economic sociologist:

 Michel Callon (1945–2025): A life with passion for economies
Koray Caliskan &Alexandre Mallard, Journal of Cultural Economy, Published online: 15 Dec 2025 https://doi.org/10.1080/17530350.2025.2595423 

 "Readers of the Journal of Cultural Economy will likely remember Michel Callon for the remarkable line of inquiry into markets that he initiated in the 2000s. Yet to recall how he approached the economy throughout his intellectual journey – and how, in doing so, he transformed our very understanding of economies – is a good way to honor an intellectual beacon of our times."

Bring Back the Privateers!

Senator Mike Lee has a new bill that encourages the President to authorize letters of marque and reprisal against drug cartels:

The President of the United States is authorized and requested to commission, under officially issued letters of marque and reprisal, so many of privately armed and equipped persons and entities as, in the judgment of the President, the service may require, with suitable instructions to the leaders thereof, to employ all means reasonably necessary to seize outside the geographic boundaries of the United States and its territories the person and property of any individual who the President determines is a member of a cartel, a member of a cartel-linked organization, or a conspirator associated with a cartel or a cartel-linked organization, who is responsible for an act of aggression against the United States.

SECURITY BONDS.—No letter of marque and reprisal shall be issued by the President without requiring the posting of a security bond in such amount as the President shall determine is sufficient to ensure that the letter be executed according to the terms and conditions thereof.

My paper on privateers explains how privateers were historically very successful. During the War of 1812, roughly 500 privateers operated alongside a tiny U.S. Navy. The market responded swiftly—privateers like the Comet were commissioned within days of war’s declaration and began capturing prizes within weeks. Sophisticated institutional design combined combined profit incentives with regulatory constraints:

  • Security bonds ensured compliance with license terms
  • Detailed instructions protected neutral vessels and required civilized conduct
  • Prize courts adjudicated captures and distinguished privateers from pirates
  • Share-based compensation created good incentives for crews
  • Markets emerged where crew could sell shares forward (with limits to maintain work incentives)

Privateers cost the government essentially nothing compared to building and maintaining a navy. Private investors financed vessels , bore the risks, and operated on profit-seeking principles. Moreover, privateers unlike Navy vessels had incentives to capture enemy ships, particularly merchant ships, not just blow them and their occupants out of the water. Of course, capturing the drugs isn’t very useful but it’s quite possible to go after the money on the return journey–privateers as hackers–which is just as good.

Here is my paper on privateering, here is the time I went bounty hunting in Baltimore, here is work on the closely related issue of whistleblowing rewards and here is the excellent historian Mark Knopfler on privateering:

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…

Séb Krier, continued

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.

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 [see update below], 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.

Update: It was a redacting error. Abrego Garcia’s attorneys subsequently filed a corrected version that now redacts the quote drawn from the sealed Dec. 3 court order which concluded that Associate DAG Aakash Singh had a “leading role in the government’s decision to prosecute” Abrego Garcia:

The significance for the vindictive prosecution claim is that DOJ had insisted to the judge for weeks that acting U.S. Attorney Robert McGuire alone made the decision to indict Abrego Garcia, which should foreclose any inquiry into the role of Main Justice. But internal DOJ docs now show otherwise, the judge apparently found in the still-sealed order.

★ 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 (or perhaps better said, hamstring) 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, unavoidable 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. But if alternative app marketplaces were available in the US, ICEBlock certainly should still be available. Really, it should still be available in the App Store. ↩︎︎

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.

Quoting Andrej Karpathy

In 2025, Reinforcement Learning from Verifiable Rewards (RLVR) emerged as the de facto new major stage to add to this mix. By training LLMs against automatically verifiable rewards across a number of environments (e.g. think math/code puzzles), the LLMs spontaneously develop strategies that look like "reasoning" to humans - they learn to break down problem solving into intermediate calculations and they learn a number of problem solving strategies for going back and forth to figure things out (see DeepSeek R1 paper for examples).

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.”

“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

An artist’s rendering of Rocket Lab’s Tracking Layer Tranche 3 (TRKT3) program satellites, which are built on its Lightning satellite platform. Image: Rocket Lab

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.”

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.

Finalist

My thanks to Finalist for sponsoring last week at Daring Fireball. Finalist is a remarkable, ambitious, and novel app for iPhone, iPad, and the Mac from indie developer Slaven Radic. It’s a planner — a digital take on traditional paper planners. Its motto: “Most productivity apps help you organize tasks. Finalist helps you finish them.”

One aspect of Finalist that makes it different from most to-do/task apps is that instead of setting due dates for tasks, you add tasks to specific days. This really resonates with me. With most apps in this domain, the top-level items are tasks, and tasks have (optional) due dates. With Finalist, the top-level items are days, and days have tasks and events. This might sound like I’m splitting semantic hairs but it gives Finalist a very different feel, one that’s more natural to me. If you’ve got unfinished items from yesterday, Finalist lets you move them all forward to today with one tap. Or, move some forward, and leave others behind. Or, just leave them all behind and move on. Up to you. I like that.

Finalist integrates with the system in all the ways you’d hope, including with the system calendar APIs and the Reminders app. So events in your system calendar and items from Reminders show up on your days in Finalist. Finalist lets you create events (calendar items), reminders (to-dos that are synced with Reminders), tasks (to-dos that exist only in Finalist), journal entries (like notes to yourself), and section headers if you have a busy day and need to group certain items together. Oh, and “habits”, too — recurring to-dos for habits you want to build or break. It sounds like a lot, but it all fits together neatly, covering the gamut of stuff you’d track in a daily paper planner. And everything in Finalist syncs between platforms (iPhone, iPad, Mac) with iCloud. There’s no account to create — it just uses iCloud, which is private and simple.

It’s not minimalist, but it’s not complicated. I’ve had a lot of fun learning to use Finalist just by exploring it. It’s thoughtful and intuitive. Like any civilized app, Finalist’s tags allow you to include spaces and capital letters in tag names, and don’t start with a stupid # character. And, design-wise, Finalist is very handsome — it offers customizable color themes and makes terrific use of the typographic features of the San Francisco system font.

Subscriptions cost $5/month or $30/year. A lifetime license costs just $60. It supports Family Sharing too.

I’m kind of blown away by how robust and thoughtful Finalist is. It’s not a web app with iOS and Mac clients. It’s a suite of native apps designed with care for Apple’s platforms. Auteur software, with a distinctive brand and vision, while remaining idiomatically native. Bravo to Slavic. I strongly encourage you to check it out.
