Anthropic Researcher: “The People Building AI Earnestly Believe That It Could Kill Us All By The End Of The Decade”
September 9th, 2026I 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.

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.
