Points and comments are a snapshot, not live.
Demis Hassabis becomes Google DeepMind chair and Alphabet chief scientist; Jeff Dean departs.
Sundar Pichai announced leadership changes at Google DeepMind. Demis Hassabis will serve as Chair of GDM and Chief Scientist of Alphabet, continuing at Isomorphic Labs. Koray Kavukcuoglu becomes SVP of Google DeepMind, overseeing Gemini model development and research. Jeff Dean and Sanjay Ghemawat are leaving to launch Discovery Loop, an independent public benefit corporation focused on ML, science, and engineering, with Google as an investor and cloud partner. Hassabis said he wants to focus on strategic AGI matters and accelerating Isomorphic Labs' drug discovery mission.
What commenters are saying
Commenters saw the shakeup as significant, with several noting recent high-profile departures and Gemini 3.5 Pro delays as signs of internal turmoil. Two camps emerged: those viewing Demis's move as a promotion toward a future Alphabet CEO role, and those seeing it as a step away from day-to-day power. The thread also discussed Jeff Dean's legacy, highlighted by the 'Jeff Dean Facts,' and questioned whether the new company, Discovery Loop, can succeed given Google's past AI lead erosion. Some speculated the changes were timed to minimize disruption.
