Senior AI researcher who resigned from Anthropic: "We are gambling with our lives"

Jacob Coxson, a senior AI researcher at Anthropic, resigned and announced a complete departure from the field of artificial intelligence, warning against the development of uncontrollable systems with self-improvement capabilities that could endanger humanity.

Jacob Coxson, a senior researcher at Anthropic, a company specializing in artificial intelligence, resigned and announced he would leave the field of AI entirely. This was reported yesterday (Tuesday) by the Wall Street Journal. The move came at a sensitive time for the company, which is in advanced IPO processes. Coxson published a long post on X, in which he stated he is "concerned that tech giants are rushing to develop uncontrollable systems with self-improvement capabilities." He claimed he is leaving the company because he does not want to participate in the race to build systems that can improve themselves, and out of fear that such systems could spiral out of control and destroy humanity. Coxson previously worked at OpenAI and joined Anthropic earlier this year, working on pre-training and data processing for frontier models. His departure, as a key data expert, is expected to impact data pipeline optimization and the training pace of next-generation models like Claude 4. "Do not underestimate the power of this technology," Coxson said. "These will soon be superhuman systems capable of breaking into anything, transforming every field overnight, and acquiring real power and resources." He added: "The people building AI firmly believe it could kill us all by the end of the decade. This is not a marketing gimmick."
