Anthropic Researcher Quits Over AI Extinction Fears

Anthropic pretraining researcher Jacob Coxon resigned, warning that AI labs are gambling with human lives. His viral X posts cited fears about recursive self-improvement, systems that could hack anything and acquire real power. Anthropic's own alignment science lead confirmed the concern, stating he personally believes AI has over a 10% chance of killing all humans within a decade. The resignation triggered responses from lawmakers, investors, and industry figures. Senator Bernie Sanders announced plans to introduce legislation banning superintelligence, while Representative Lori Trahan called on Congress to act. Investors noted the controversy could affect Anthropic's upcoming IPO, demanding the existential risk be disclosed in its S-1 filing.
