If you are helping build something that might kill everyone, maybe stop doing that.

Ideally, when you do stop, tell everyone else to also stop building it.

That is certainly the obvious, first-level thing to do. You need a damn good reason to decide that no, actually you should keep building the thing that might kill everyone.

Scott Alexander is worried too many people are insisting upon this too loudly. He comes out against a strategy focused on getting people to stop. I disagree. I think many of the claims, arguments and rhetoric in Scott's post are quite poor by the standards that Scott Alexander would apply to himself.

Scott clearly continues to support advocacy for a global pause, or what he calls Plan A. His objection is to those advocating primarily or exclusively for SURA, which stands for ‘stop unilaterally and raise awareness.’ The practical differences here are smaller than they may at first appear.

This post first lays out my understanding of Scott Alexander's core claims, then gives my core reactions to those claims, then goes over various questions in detail along with gathering the resulting discussions.

Nikole Hannah-Jones wrote a brave self-critical piece in The New York Times, centrally about how she intentionally sent her daughter to a well-funded but failing school, PS 307, in the hopes of using voice to improve it, and how that utterly failed her daughter and failed to impact the school.

Ultimately her daughter recovers, but we see a completely broken system that is unresponsive to internal voice, and until now she made no attempt to blow the whistle and utilize her professional position to do so.

The whole incident illustrates not only how messed up so many of our schools are despite abundant funding, it also raises the question of what the schools are even for. If her daughter can fully recover from severe deficits and be getting As and Bs at a challenging school within a year, what are the first eight years of school for? How much of the schools, grades and tests are fake? Can we somehow do better?

Anthropic filed its S-1 this week to prepare for its IPO. They still have to fill a lot of the numbers including the share price. That still left a lot to be learned, including how the messaging to investors differs from their other rhetoric, and exactly how their corporate control is structured. Anthropic remains a frustrating company, doing a variety of things that often seem in tension with each other.

Google is claiming to be fully back, with the announcement of a new model Gemini 4 Carbon that tops the new AA v5 benchmark index. It looks to be a large leap over Argon only two weeks later. No, you cannot use it. Google fails marketing forever, so they give us the announcement and then weeks later you might be able to enter some queries. That largely invalidates my look at the Argon model and safety cards, but it can at least form a basis for looking at Carbon as well.

Many eyes remain on The Hackening, as additional things get hacked. So far most of the important hacks have been by read teamers and white hats, so there has not been major damage. We are playing [...]

The full text is finally here, so we are giving it the full RTFB of model card treatment.

First, a recap of the state of Anthropic finances, then a close reading of the relevant parts of the S-1. A lot of it is technical and uninteresting, often pro forma, and gets skipped. A lot of it gets repeated many times.

A lot of this is also Anthropic ‘playing the hits’ we have heard many times, now to the investor circuit. Get your drinks ready for when we have to maximize the upside and minimize the downside.

This presentation of S-1 data has some cool Claude-created charts if that's your jam.

Here are my top 10 takeaways from the S-1, for those already familiar with Anthropic.


Existential risk is mentioned briefly only in the passive voice, and alignment issues are mostly treated as prosaic. They want to claim Big Mission but also sound as much as possible like a normal company. They are downplaying their willingness to pay real costs for safety, and downplaying the danger quite a lot.

‘Pacing the Frontier’ is not something they will do on their own. They’ll do [...]

Anthropic is a frustrating company.

Sometimes it will do things I greatly appreciate, including at substantial cost. They have taken bold stands, have a unique governance structure and have hired and worked to establish a relatively strong (but I think still inadequate) safety culture.

Other times, it will do things that are deeply disappointing.

It produces very good models. That too is not entirely a good thing.

One can both be the best given the alternatives, and insufficient to meet the moment.

Ultimately, what you think about Anthropic depends on what parts you care about most, and what you think would be sufficient.

Anthropic is great if you think the problems are important and difficult, but within the range of what Anthropic's approaches can solve. If you think we mainly need operational excellence and caring about safety and the future, then there are some non-excellent operations to fix but that goal seems doable for Anthropic. If you think the problems go well beyond that, then things look rather grim for everyone.

Today's post begins with a continuation of discussion over Anthropic's leaked draft bill. See my previous coverage for details of the [...]
