I Am Retiring from Tech to Live Offline
Simon Willison's Weblog2d agoEthicsSimon Willison highlights Chad Whitacre’s decision to leave tech and Open Source, framed not as a forum threat but as concrete action. Whitacre describes wanting to become “AI Amish” or “Internet Amish,” moving toward an offline, analog life closer to 1980 than 1780. A previous post about using Claude Code with Opus 4.5 shows how agentic AI felt intoxicating and unsettling enough to push him away from technological accelerationism.
