“The people building AI earnestly believe that it could kill us all by the end of the decade,” Coxon said. “I spent the last three years doing pre-training research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives.”

Anthropic’s current head of alignment re-posted Coxon, noting that he is “correct” that “we really do earnestly believe AI could kill all humans!” He estimates there’s a greater than 10% chance it could happen within the next decade. And earlier this week, OpenAI’s head of research Jakob Pachocki published a blog post outlining his concerns for humanity.

Not great. So what do we do about it?

This is the first time an AI warning has truly gone mainstream

While Coxon is far from the first to warn about the perils of AI, his message might be the first to truly break into the mainstream. He promptly went on a media tour the same day he posted on X, and his message captured headlines at top news organizations. Even country singer Sheryl Crow urged her Instagram followers to take him seriously.
