Former Anthropic Researcher’s Viral AI Warning Intensifies Debate Over Frontier Model Safety

A former Anthropic and OpenAI researcher’s public resignation has pushed AI safety concerns back into the center of the industry debate, after his warning about a race toward self-improving superintelligence was reported to have reached more than 100 million people and later more than 171 million views. Jacob Coxon, described as a 27-year-old researcher who spent three years working on pretraining research at Anthropic and OpenAI, said he left Anthropic because leading labs were moving too quickly toward systems that could become harder to control.
