Dario Amodei: 'Why Argue With Someone You Don't Trust' — Anthropic CEO Explains Why He Left Sam Altman and OpenAI

In a Bloomberg interview, Anthropic CEO Dario Amodei made trust the centerpiece of his explanation for leaving OpenAI in 2021, saying 'Why argue with someone when you don't have the same vision and you don't trust them?' — a clear implicit reference to Sam Altman. Amodei said he is 'completely at peace' with the two labs pursuing separate paths and believes 'the market and public opinion' will determine which approach succeeds. He contrasted his lack of trust in Altman with his view of Google DeepMind CEO Demis Hassabis as trustworthy, framing cross-company AI safety cooperation around which leaders can be relied upon.
