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 left Google after 27 years to co-found Discovery Loop with Sanjay Ghemawat, Oriol Vinyals and Quoc V. Le, and his pitch deck surfaced a list of 34 founders who came out of Google Brain — evidence that Brain has become the single largest talent pipeline feeding today's AI startup wave.

• Discovery Loop targets AI for Science: full automation of machine learning, scientific discovery and engineering, framed around "recursive self-improvement" — packaging an "automated AI scientist" so a handful of researchers can outpace large institutions.
• The four co-founders' Google track record spans the infra era (GFS, MapReduce, BigTable, Spanner/TrueTime, Borg, LevelDB, TCMalloc) and the deep learning era (Google Brain, the 2012 unsupervised "cat" experiment, TensorFlow, TPUs, Seq2Seq, AutoML/NAS, chain-of-thought, AlphaStar, Gemini co-lead and Gemini 3 "Deep Think" reasoning).
• The alumni list includes Dario Amodei (Anthropic), Ilya Sutskever (SSI), Chris Olah (Anthropic) and Yang Zhilin (Moonshot AI, mentored by Quoc Le); the article credits the 2016 Brain Residency program, which recruited on quantitative aptitude, self-driven AI passion and cross-disciplinary background rather than AI PhD pedigree.
• Article notes the departure (dated 2026-08-05) coincided with significant Alphabet stock volatility; per the piece, SSI is also expected to unveil its first model this month.
