Jacob Coxin, an AI researcher formerly at OpenAI and most recently at Anthropic, resigned citing fears that AI could lead to human extinction by the end of the decade. He posted his concerns on X, which went viral, attracting significant attention and sparking debate about AI safety and regulation.

“neither Open AI nor Anthropic, ostensibly, is acting responsibly. They're not acting responsibly, Sax.”
“they are racing straight to self-improving super intelligence and gambling. Gambling with our lives.”
