People would quake in their boots at his design reviews. This was sort of like taking your orals for your dissertation. He would have a hand-picked collection of people in the audience and you would have to present your design. The people he picked were always good. The thing that made his design reviews so scary is he knew when you were bluffing.

I’m sure you’ve done design reviews where you didn’t work on some part of it real well and so you kind of slide past that part. You think you got this right but you didn’t really do the analysis so you don’t know quite what’s going on. He had an instinct, and it was abetted by having a good crew in there, of catching you when you were bluffing, catching you when you hadn’t thought it through.

The parts that you did absolutely fine hardly got a mention. We all said, “O
