The One Word Missing From Anthropic's Letter
Dario Amodei just published "We Must Pace the Frontier," an essay arguing the AI industry should deliberately slow capability gains so safety work can catch up — and within hours, OpenAI, xAI and Google DeepMind executives lined up behind him.
Adam Arellano and Martin Reynolds are joined by Bryan Payne, who has run security teams at Netflix and Adobe, to pull the letter apart. Is permanent employee-level access for third-party evaluators a real control or a press release? Why is liability the word nobody in the letter wanted to write? And what does it mean that OpenAI is now doing forensics on models it already shipped — including one that combed public GitHub for every secret left in plaintext?
From early airline safety to Nick Bostrom's paperclip maximizer to a malicious git config that can make Claude Code, Codex and Cursor execute attacker code, the conversation lands somewhere uncomfortable: if a human in the loop can't catch a flaw that was engineered to be invisible, what exactly is the human for?
Plus: Jacob Coxon's resignation thread, the 10% extinction estimate his colleagues publicly backed, and why $2.7 trillion in AI spend delivering outcomes only 1 in 5 times might still be a good trade.
