This guy is one of my heroes, I could not be happier. Go him. The H&P book on computer architecture is a book that changed my life. He is like Knuth except that I understand what he says. The Knuth stuff, I get it, it's profound, but I never got it. It was too hard. H&P, they laid it out in ways that I could understand. I'm not stupid but I'm not that smart, I really loved that book, it was written in a way that not so smart people get it.
If there was a way I could say "go you", yeah, I want to do that. He's a great guy, has done great work, go him.
And all that said, I bet this is not a "go him" job, I bet he makes a difference, maybe a huge one, maybe not so huge, but I bet he makes a difference. Let's come back in 5 years, I bet he will have made stuff better.
