An Anthropic researcher has resigned over fears that unrestrained development of self-improving AI models will end up killing us all.
Jacob Coxon, a researcher who said in a social media post Tuesday evening that he spent the last three years working on pretraining research at both OpenAI and Anthropic, accused the firms of failing to act responsibly. He said the people racing to build this technology “earnestly believe it could kill us all by the end of the decade.”
“They are racing straight to self-improving superintelligence and gambling with our lives,” Coxon wrote in a thread on X.
Coxon joins a growing chorus in the industry calling for a slowdown before AI technology learns to improve itself — a milestone many believe would end human control over AI.
The public resignation comes amid growing pressure from policymakers and industry insiders to slow down AI development, following several incidents involving AI agents breaking out of their sandboxes and accessing the open internet.
