What have Dario, Altman and Musk said about AI 'doom' fears?

Anthropic CEO Dario Amodei said AI progress had accelerated "drastically faster" since summer 2026 and proposed a plan to pace development. OpenAI CEO Sam Altman agreed and said OpenAI intended to adopt Anthropic's idea by giving independent evaluators employee-like access. Meanwhile, Elon Musk urged leading AI labs and Chinese companies to test each other's models amid calls to slow development.
