Anthropic researcher Jacob Coxon’s resignation and warnings that advanced AI could destroy humanity have intensified a public dispute over the technology’s risks, business incentives and potential regulation. Coxon, 27, previously worked at OpenAI and said developers were gambling with people’s lives as systems approached superhuman capabilities. Anthropic team lead Evan Hubinger said he personally put the chance of AI killing all humans at more than 10% within the next decade. The comments drew criticism from Grindr CEO George Arison, Nvidia CEO Jensen Huang, Altimeter Capital chief Brad Gerstner and Hugging Face CEO Clement Delangue, while Anthropic CEO Dario Amodei called for slower model development and global rules. The debate comes as Anthropic and OpenAI pursue valuations of $965 billion and $852 billion, respectively, and prepare for possible public offerings. It has also revived scrutiny of Anthropic’s Mythos cybersecurity tool, alleged misuse of AI for bioweapons and cyber-espionage, and proposed restrictions including Senator Bernie Sanders’ temporary pause on advanced AI development.
