刚刚！谷歌之神创业，带走最顶尖AI天团，杀入AI4Science

TL;DR - Google chief scientist Jeff Dean is leaving after 27 years to co-found Discovery Loop, a public benefit corporation with three longtime Google AI/systems veterans, aimed at automating the scientific discovery loop. It signals that AI4Science is becoming the next strategic battleground for top AI talent after code.

• Founding team: Jeff Dean (MapReduce, Google Search infra), Sanjay Ghemawat (GFS, systems), Oriol Vinyals (research, AlphaFold/Gemini lineage), and Quoc Le (automated ML) — roles largely mirror their Google responsibilities.
• Core thesis: today's science is a slow, labor-intensive trial-and-error loop; Discovery Loop wants systems that autonomously generate hypotheses, design experiments, run them, and iterate — enabling thousands of parallel experiments.
• First milestone is automating ML research and engineering itself; the longer-term target is NAE Grand Challenges (better drugs, health informatics, economical solar, clean water, cyberspace security, discovery tools).
• Framing note per the article: Vinyals has publicly argued human scientists remain essential for asking the right questions and steering AI. Company details beyond the website mission (funding, timeline) are not given in the source.
