AI Stars Bolt Google for Rivals
22 Jun
Summary
- Two top AI researchers left Alphabet for competitors.
- One co-created AlphaFold, a drug discovery tool.
- Stock dropped $250 billion following the departures.

Alphabet's stock experienced a significant tumble, shedding $250 billion in market capitalization following the recent departures of two key artificial intelligence researchers. John Jumper, a senior research scientist at Google DeepMind and Nobel prize winner, has joined Anthropic. Jumper was instrumental in co-creating AlphaFold, an AI tool that predicts protein structures, potentially accelerating biological and medical research.
Adding to Alphabet's challenges, Noam Shazeer, a vice president of engineering and co-lead of the company's Gemini AI models, has also left. Shazeer has reportedly joined OpenAI. While these departures represent a loss of valuable talent, the extent of the market's reaction prompts discussion about whether individual employees' impact justifies such a substantial financial downturn.
