Jeff Dean 创业路演 PPT，惊现 34 位创始人，谷歌系人才占领半壁江山

TL;DR - Jeff Dean is leaving Google after 27 years to co-found Discovery Loop, an AI-for-Science startup, and his pitch deck exposed a roster of 34 founders who came out of Google Brain — a map of how one lab seeded much of today's AI startup landscape.

• Discovery Loop's co-founders are Jeff Dean, Sanjay Ghemawat, Oriol Vinyals and Quoc V. Le; the stated goal is full automation of machine learning, scientific discovery and engineering — i.e. "recursive self-improvement" packaged as an automated-AI-scientist service.
• The deck's alumni list includes Dario Amodei, Chris Olah and Tom Brown (Anthropic), Ilya Sutskever (SSI), and Yang Zhilin (Moonshot AI, mentored by Quoc Le at Brain).
• The article credits Brain's 2016 Residency program, which deliberately recruited non-CS backgrounds (physics, math, biology, dropouts) on quantitative aptitude, self-driven AI passion and cross-disciplinary perspective, with mentorship from Dean, Hinton or Le.
• Departures land at a peak moment — Gemini 3 "Deep Think" reasoning gains are attributed to Le's team, Vinyals co-led Gemini's native-multimodal architecture — and reportedly moved Alphabet's stock.
