A message from Guido Reichstadter, who is on hunger strike outside Anthropic's offices

I am somewhat in two minds about the leading AI company Anthropic. On one hand, they are pretty much the world's best AI safety lab, producing so much extraordinarily interesting work, such as their papers on Alignment faking in large language models and on Agentic misalignment. For that I love them. On the other hand, that work is deeply insufficient for robustly protecting against AI apocalypse, and yet they push full speed ahead on capabilities in a way that makes them one of the main contributors to the reckless race towards the AGI precipice. For that I detest them.

Those are mixed feelings. On balance, though, I do not think their work on AI safety makes up for their reckless endangering of all of our lives.

An increasing number of people are reaching a similar conclusion, including in particular Guido Reichstadter, who is currently on his 8th day of hunger strike outside Anthropic's offices in San Francisco.¹ For this, he has my deepest admiration and respect. Here is his message from yesterday:

Hey it’s Guido! It’s Day 7 out here in front of Anthropic, going strong!

Last week I delivered a letter to the security desk addressed to Dario Amodei, asking him to stop putting the lives of my family and our community in danger through his reckless participation in the race to dangerous AI which he acknowledges risks the lives of everyone on Earth, and to do everything in his power to stop the global AI race. I told him I would be waiting outside his offices at 500 Howard Street, San Francisco, untill he responds.

I figure that if a man has consciuosly decided to put my life at risk of imminent harm, as well as the lives of my family - not to mention everyone on Earth - he owes it to me to look me in the eyes and tell me why he won’t stop doing so.

I’ve been outside his offices for 7 days so far, and haven’t heard a word from Mr. Amodei. Not a single Anthropic employee has taken the time of day to talk to the man starving outside their doors. Most of them keep their eyes to the ground as they leave the lobby I’m posted squarely in front of, as though the granite flooring had suddenly captured their attention. Maybe Mr. Amodei and his employees don’t think my petition that he respect my life and the lives of our community deserves a response. Maybe he thinks my right to life and the lives of my family deserve as much attention as a piece of dirt. If that is the case then you can be sure he thinks your life deserves as much respect too, and that’s how much he will give it as he continues to develop the most dangerous technology on the planet.

I believe that Mr. Amodei will conduct himself honorably and explain himself face to face. I worry perhaps that he might not have got my letter though, so I’m posting it publicly to him here. And I’d like to encourage everyone reading this to share this to the public accounts of Mr. Amodei and all the Anthropic employees, and to encourage him to meet with the man waiting outside his door.

Here is the text of the letter I delivered to the front desk of Anthropic’s offices at 500 Howard street:

To Dario Amodei, CEO Anthropic
September 2, 2025

Mr. Amodei-
My name is Guido Reichstadter. I am full of grief and concern for the safety and well-being of my family and loved ones as well as people everywhere who are endangered by the project to build artificial general intelligence and superintelligence which Anthropic is contributing to under your leadership.

I request that you stop endangering all of us by the pursuit of these AI systems and request that you join the effort to end this threat by ending these projects globally. I also exhort you to do everything in your ability to make our society aware of the serious and urgent danger it is in on account of the AI emergency.

For the sake of my children and with the urgency and gravity of our situation in my heart I have begun a hunger strike outside of the Anthropic offices at 500 Howard street while I await your response.

Sincerely,
Guido Reichstadter

Well said! And surely Dario Amodei will grant Guido Reichstadter a meeting? If and when that happens, I have a paper which I completed last month and which I believe can be useful as discussion material for that meeting: Advanced AI and the ethics of risking everything.

I find Sam Altman's latest words on AI timelines alarming

Estimating timelines until AI development hits the regime where the feedback loop of recursive self-improvement kicks in, leading towards the predictably transformative¹ and extremely dangerous intelligence explosion or Singularity, and superintelligence, is inherently very difficult. But we should not make the mistake of inferring from this lack of predictability of timelines that they are long. They could be very short and involve transformative changes already in the 2020s, as is increasingly suggested by AI insiders such as Daniel Kokotajlo, Leopold Ashcenbrenner and Dario Amodei. I am not saying these people are necessarily right, but to just take for granted that they are wrong strikes me as reckless and irrational.

And please read yesterday's blog post by OpenAI's CEO Sam Altman. Parts of it are overly personal and cloying, but we should take seriously his judgement that the aforementioned regime change is about to happen this very year, 2025:

We are now confident we know how to build AGI as we have traditionally understood it. We believe that, in 2025, we may see the first AI agents “join the workforce” and materially change the output of companies. We continue to believe that iteratively putting great tools in the hands of people leads to great, broadly-distributed outcomes.

We are beginning to turn our aim beyond that, to superintelligence in the true sense of the word. We love our current products, but we are here for the glorious future. With superintelligence, we can do anything else. Superintelligent tools could massively accelerate scientific discovery and innovation well beyond what we are capable of doing on our own, and in turn massively increase abundance and prosperity.

This sounds like science fiction right now, and somewhat crazy to even talk about it. That’s alright—we’ve been there before and we’re OK with being there again. We’re pretty confident that in the next few years, everyone will see what we see, and that the need to act with great care, while still maximizing broad benefit and empowerment, is so important. Given the possibilities of our work, OpenAI cannot be a normal company.

The time window may well be closing quickly for state actors (in particular, the U.S. government) to intervene in the deadly race towards superintelligence that OpenAI, Anthropic and their closest rivals are engaged in.
