Google AI Leadership Shakeup

Major leadership reshuffle at Google DeepMind: Demis Hassabis steps aside as CEO to become chief scientist/chair, Jeff Dean leaves to start Discovery Loop. This signals Google's struggle to keep pace with OpenAI/Anthropic, with Gemini 3.5 Pro reportedly months behind due to low morale and talent exits. Stock drop and upbeat memos mask underlying turbulence. For PM/PMMs tracking AI industry dynamics, this is a critical signal about talent flight, organizational friction, and competitive pressure at a key frontier lab.
