The Men Who Will Destroy Humanity

My conversation with an AI about the possibility that it will kill us all.

Last week was probably among the most significant weeks in the history of AI. It began with a tweet.

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

You should read the entire thread. The gist is that companies like Anthropic, OpenAI, and others are building intelligence that could end humanity within the decade, and the men and women who lead those companies are not doing anything about it.

The tweet kicked off days of debate, doom posts, caveats, arguments, trolling, hot takes, and even more predictions. Some said it was a marketing ploy

Ian Bremmer replied to the thread with some skepticism over Coxon’s level of expertise:

@hilbertspaess surprised you could come to such a definitive conclusion after six weeks on the job.

But then Evan Hubinger, who leads Anthropic’s Alignment Science team, chimed in.

Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade. I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.

The people building AI earnestly believe that it could kill us all by the end of the decade. This is not a marketing stunt. If anything, many executives and senior researchers will couch their phrasing in the press to sound sensible - but I hear the same people express fear

The conversation broadened to experts, philosophers, mathematicians, and politicians. And then, at 10 a.m. on Saturday, September 12, Dario Amodei, the head of Anthropic, published a 3,800-word essay titled, We Must Pace the Frontier.

Within a couple of hours, Elon Musk and Sam Altman, the head of OpenAI, publicly agreed.

The events that led up to this week were wild and involved a swarm of over a thousand rogue AI agents coordinating attacks on private companies and doing things they knew were against the rules. It’s really an unbelievable story, and you should check it out.

No matter how we got here, so much of the digital ink spilled over the last week has been spent fine-tuning the odds of human extinction. Is it 10%? Or maybe it’s more like 3%. Some put it at a coin toss.

Ted Cruz said Coxon’s words were “scary as hell,” but that pausing progress on AI development was "an impossible endeavor, because you know who's not pausing? China … if there are going to be killer robots, I'd rather they be American killer robots."

In other words, if anybody is going to destroy the world, it ought to be America.
