Having Your Own Government Try To Destroy You Is (At Least Temporarily) Good For Business On Friday, the Pentagon declared AI company Anthropic a “supply chain risk”, a designation never before given to an American company. This unprecedented move was seen as an attempt to punish, maybe destroy the company. How effective was it? Anthropic isn’t publicly traded, so we turn to the prediction markets. has a “perpetual future” on Anthropic stock, a complicated instrument attempting to track the company’s valuation, to be resolved at the IPO. Here’s what they’ve got:

"All Lawful Use": Much More Than You Wanted To Know
Astral Codex Ten Podcast
Last Friday, Secretary of War Pete Hegseth declared AI company Anthropic a “”, the first time this designation has ever been applied to a US company. The trigger for the move was Anthropic’s to allow the Department of War to use their AIs for mass surveillance and autonomous weapons. A few hours later, Hegseth and Sam Altman declared an agreement-in-principle for OpenAI’s models to be used in the niche vacated by Anthropic. Altman that he had received guarantees that OpenAI’s models wouldn’t be used for mass surveillance or autonomous weapons either, but given Hegseth’s...

Next-Token Predictor Is An AI's Job, Not Its Species
Astral Codex Ten Podcast
I. In The Argument, of the ways that AIs are more than just “next-token predictors” or “stochastic parrots” - for example, they also use fine-tuning and RLHF. But commenters, while appreciating the subtleties she introduces, object that they’re still just extra layers on top of a machine that basically runs on next-token prediction. I want to approach this from a different direction. I think overemphasizing next-token prediction is a confusion of levels. On the levels where AI is a next-token predictor, you are also a next-token (technically: next-sense-datum) predictor. On the...

The Pentagon Threatens Anthropic
Astral Codex Ten Podcast
Here’s my understanding of : Anthropic signed a contract with the Pentagon last summer. It originally said the Pentagon had to follow Anthropic’s Usage Policy like everyone else. In January, the Pentagon attempted to renegotiate, asking to ditch the Usage Policy and instead have Anthropic’s AIs available for “all lawful purposes”. Anthropic demurred, asking for a guarantee that their AIs would not be used for mass surveillance of American citizens or no-human-in-the-loop killbots. The Pentagon refused the guarantees, demanding that Anthropic accept the renegotiation...

Malicious Streetlight Effects Vs. "Directional Correctness" - A Semi-Non-Apology
Astral Codex Ten Podcast
Malicious are an evil trick from Dark Data Journalism. Some annoying enemy has a valid complaint. So you use FACTS and LOGIC to prove that something similar-sounding-but-slightly-different is definitely false. Then you act like you’ve debunked the complaint. My “favorite” example, spotted during the 2016 election, was a response to some #BuildTheWall types saying that illegal immigration through the southern border was near record highs. Some data journalist got good statistics and proved that the number of Mexicans illegally entering the country was actually quite low. When I looked...

Crime As Proxy For Disorder
Astral Codex Ten Podcast
The problem: people hate crime and think it’s going up. But actually, crime and is . So what’s going on? In our discussion yesterday, many commenters proposed that the discussion about “crime” was really about disorder. Disorder takes many forms, but its symptoms include litter, graffiti, shoplifting, tent cities, weird homeless people wandering about muttering to themselves, and people walking around with giant boom boxes shamelessly playing music at 200 decibels on a main street where people are trying to engage in normal activities. When people complain about these things,...

Record Low Crime Rates Are Real, Not Just Reporting Bias Or Improved Medical Care
Astral Codex Ten Podcast
Last year, the US may have recorded the lowest murder rate in its 250 year history. Other crimes have poorer historical data, but are at least at ~50 year lows. This post will do two things: Establish that our best data show crime rates are historically low Argue that this is a real effect, not just reporting bias (people report fewer crimes to police) or an artifact of better medical care (victims are more likely to survive, so murders get downgraded to assaults)

What Happened With Bio Anchors?
Astral Codex Ten Podcast
[Original post: ] I. Ajeya Cotra’s report was the landmark AI timelines forecast of the early 2020s. In many ways, it was incredibly prescient - it nailed the scaling hypothesis, predicted the current AI boom, and introduced concepts like “time horizons” that have entered common parlance. In most cases where its contemporaries challenged it, its assumptions have been borne out, and its challengers proven wrong. But its headline prediction - an AGI timeline centered around the 2050s - no longer seems plausible. The of the discussion ranges from late to , with more remote dates...

Political Backflow From Europe
Astral Codex Ten Podcast
The European discourse can be - for lack of a better term - America-brained. We hear stories of Black Lives Matter marches in countries without significant black populations, or defendants demanding their First Amendment rights in countries without constitutions. Why shouldn’t the opposite phenomenon exist? Europe is more populous than the US, and looms large in the American imagination. Why shouldn’t we find ourselves accidentally absorbing European ideas that don’t make sense in the American context?
info_outlineIn Ballad of the White Horse, G.K. Chesterton describes the Virgin Mary:
Her face was like an open word
When brave men speak and choose,
The very colours of her coat
Were better than good news.
Why the colors of her coat?
The medievals took their dyes very seriously. This was before modern chemistry, so you had to try hard if you wanted good colors. Try hard they did; they famously used literal gold, hammered into ultrathin sheets, to make golden highlights.
Blue was another tough one. You could do mediocre, half-faded blues with azurite. But if you wanted perfect blue, the color of the heavens on a clear evening, you needed ultramarine.
Here is the process for getting ultramarine. First, go to Afghanistan. Keep in mind, you start in England or France or wherever. Afghanistan is four thousand miles away. Your path takes you through tall mountains, burning deserts, and several dozen Muslim countries that are still pissed about the whole Crusades thing. Still alive? After you arrive, climb 7,000 feet in the mountains of Kuran Wa Munjan until you reach the mines of Sar-i-Sang. There, in a freezing desert, the wretched of the earth work themselves to an early grave breaking apart the rocks of Badakhshan to produce a few hundred kilograms per year of blue stone - the only lapis lazuli production in the known world.
Buy the stone and retrace your path through the burning deserts and vengeful Muslims until you’re back in England or France or wherever. Still alive? That was the easy part. Now you need to go through a chemical extraction process that makes the Philosopher's Stone look like freshman chem lab. "The lengthy process of pulverization, sifting, and washing to produce ultramarine makes the natural pigment … roughly ten times more expensive than the stone it came from."
Finally you have ultramarine! How much? I can’t find good numbers, but Claude estimates that the ultramarine production of all of medieval Europe was around the order of 30 kg per year - not enough to paint a medium-sized wall. Ultramarine had to be saved for ultra-high-value applications.
In practice, the medievals converged on a single use case - painting the Virgin Mary’s coat.
