Agents Built an OS Kernel That Runs Doom — Kevin Hou, Google DeepMind

Why watch

Kevin Hou of Google DeepMind presents Antigravity, an agentic coding product that used 93 subagents to build an OS kernel from scratch in 12 hours using 2 billion tokens. He explains the evolution from autocomplete (2022) to agent teams (2026), the three building blocks of Antigravity 2.0 (dynamic subagents, sidecars, generative UI), and lessons learned from product decisions like removing chat from Windsurf. The video is for engineers and product managers interested in the future of AI-powered development tools.
