John Giannandrea is the former Senior Vice President of Machine Learning and AI Strategy at Apple, and former head of Search and AI at Google. Earlier he worked at General Magic and Netscape, and was CTO of Tellme and of Metaweb, which Google acquired in 2010. John joins Brad Porter, who worked for him at Tellme, to talk about ideas that arrive 20 years too early, the day he saw the web and quit his job, why skeptics are a good sign, and how to know when an AI system that is never 100% right is ready to ship. The conversation ultimately points toward a future where the next leap in AI comes from better architectures and a deeper understanding of the models, and where the teams that win, in software or robots, set a launch bar, ship into real work, and keep climbing. 0:00 Intro1:33 From Scotland to Silicon Valley: Inmos, Pixar, and SGI4:15 General Magic: building the iPhone 15 years too early5:18 Seeing Mosaic, quitting, and joining Netscape as employee #208:42 AOL buys Netscape and the move to Tellme11:43 Open-sourcing the browser: the road to Firefox13:32 Metaweb, Danny Hillis, and building the knowledge graph17:54 How Metaweb disrupted Google Search21:57 Google's AI second act and the $15K espresso machine24:41 Leading Google Search: a policy job, not a technical one27:23 Leaving Google for Apple: two opposite cultures31:48 Hill climbing: how ML features get to launch33:26 Beyond data and compute: the next architecture breakthrough35:08 Physical AI and why more data isn't enough36:56 Privacy, Apple Intelligence, and Private Cloud Compute40:08 Shipping LLMs: Siri, Gemini, and ChatGPT's surprise hit41:24 AI risk: what Geoffrey Hinton actually worries about42:41 The Vatican cardinal and the "200-year experiment"44:35 Was the internet a good thing?
