I joined 17 years ago to work for "a startup within the company". We were ramping up our group fast to design a product for an new market. 4 months later, Jensen sees that product at CES. Ours would be only be ready 2 years after that. The next Monday, he joined our weekly meeting and announced that our group was cancelled immediately and we'd be spread to existing BUs the next day. His words at that meeting: "Every morning when I wake up, I look in the mirror and check if the core assumptions on which I based my decisions are still valid. If not, I make the change immediately."
So refreshing when you've come from a company where everyone knew a project was doomed, but nobody had the guts to pull the plug for months.
Same thing happened a year later: we had a chip that was ready to tape out. That project was canceled on January 10th, 2007, because something happened the day before.
