A researcher who spent three years doing pretraining work at both OpenAI and Anthropic announced his resignation, accusing neither lab of acting responsibly as both race toward self-improving superintelligence.

Related commentary argues calling the discloser a "whistleblower" is inaccurate since the information was already public: the AI industry has repeatedly warned for years its tech might end humanity — the only difference now is people are starting to pay attention.
