X (formerly Twitter)Tomorrow will be my last day at Google after 27 years, and watching it grow from 25 people to 190,000+ has been an amazing journey. Below is a note I shared with many people internally at Google today. An excerpt is: It has been an absolute pleasure to work with you and to help
Open sourceRecommended because
This is worth tracking because it is a concrete industry signal, not just a passing headline. The source preview points to a market, policy, platform, labor, or investment shift. For builders and operators, "Tomorrow will be my last day at Google after 27 years， and watching it grow from 25 people to 190，00…" can be used as a checkpoint for market timing, positioning, risk assessment, and partnership decisions. I keep this thread indexed so future searches around AI industry trends, market shifts, and platform strategy can land on a source-linked page instead of disappearing into a fast-moving feed from X (formerly Twitter).
