I was lucky enough to have a long email conversation with him around 10 years back. That was where he shared the bet with Widlar. He actually contacted me, because he worked out that (feel sorry for my wife at this point) I am a Tektronix test gear collector and restorer as a hobby. The conversation moved progressively to AI, which he was agnostic about - but he reckoned the future was in Augmented Reality, where embedded computer systems would elevate our processing power and intellect. And here we are thinking 5G is a shiny new thing...
A hell of a thinker was Barrie Gilbert.
