Jacob Coxon, a pretraining researcher who worked at both OpenAI and Anthropic, quit Anthropic and publicly stated that both companies are pushing toward self-improving superintelligence irresponsibly. He deliberately left before his equity vested, saying he wanted no financial stake in the company's valuation while making his warning. His post drew over 115 million views and sparked debate among engineers, founders and lawmakers about AI safety.

A leaked resignation post from a junior Anthropic employee, who accused frontier AI companies of racing toward self-improving intelligence, spread widely and reignited public alarm over AI safety. A more senior engineer reportedly echoed internal estimates that the company's work carries roughly a 10 percent chance of catastrophic harm. In response, CEO Dario Amodei published an essay outlining a path toward safer AI, but conceded that researchers still understand only a fraction of how these models actually operate internally.

NYC DSA's Tech Action Working Group posted an Instagram carousel arguing that AI doom warnings and AI hype serve the same purpose: distracting the public from present-day harms of the technology. The post, which gained over 25,000 likes, drew backlash from commenters and highlights a growing rift among leftists, some of whom—like Senator Bernie Sanders—have embraced warnings that AI could threaten humanity's survival.

Jacob Coxon left Anthropic in September 2026, forfeiting unvested equity, after publicly claiming AI researchers privately believe their work could cause human extinction within the decade. Anthropic's alignment lead Evan Hubinger backed the claim, citing his own estimate of over 10% odds of catastrophe within ten years, while Elon Musk dismissed the episode as a publicity stunt. The controversy drew attention to the rationalist-adjacent subculture that has long shaped AI safety discourse in Silicon Valley.

Anthropic CEO Dario Amodei has proposed placing outside safety evaluators inside frontier AI companies like Anthropic and OpenAI, giving them access similar to internal risk teams and the ability to publish findings with limited redactions. He compared the idea to embedded bank examiners, but banking law expert Julie Andersen Hill says the analogy breaks down because these evaluators would have no authority to halt operations, unlike government bank supervisors who can restrict growth or shut institutions down.
