Overview
- Demis Hassabis announced on Wednesday, August 5, 2026, that he will give up day-to-day leadership of DeepMind to become the lab’s chairman and Alphabet’s chief scientist so he can focus on long‑term AGI research.
- Koray Kavukcuoglu, Hassabis’s longtime deputy, will take operational charge of DeepMind as a senior vice president reporting directly to Sundar Pichai and will oversee Gemini model and app development.
- Jeff Dean, Google’s veteran chief scientist, is leaving the company to found a new AI venture called Discovery Loop with other former Google managers.
- Alphabet shares fell about 4–5% after the announcements, a drop that translated into hundreds of billions of dollars of market value and reflected investor worry about leadership continuity and execution.
- The moves come after several recent senior researcher departures and a delayed Gemini 3.5 Pro release, raising questions about Google’s near‑term competitiveness and the balance between long‑horizon AGI research and product delivery.
