Jeff Dean and other top Google AI researchers leave to start a company

Jeff Dean, a longtime Google and DeepMind executive, is leaving Google along with other senior AI researchers to launch a new startup. The group says its mission is to use AI to accelerate scientific discovery.

Why it matters: This follows closely on reports that Dean and DeepMind's Demis Hassabis were already stepping back from day-to-day leadership, confirming that move was a prelude to a full departure rather than an internal reshuffle. Losing a researcher of Dean's stature is a significant signal, and an AI-for-science startup adds to a growing wave of similar bets by former Big Tech researchers.
