He recently wrote a book, released this year.
But for those who don't know him, he co-founded Microsoft with Bill Gates.

Kind of reminds me of Steve Wozniak, co-founder of Apple.

Steve Wozniak was basically the brains behind Apple, and never intended to monetize his inventions much. Then Steve Jobs came along.

this is usually how it works.

the smart guy is just in it for the inventions. its fucking FUN to him. and thats why hes there. thats why to really get something going you need someone to take up the business part of the deal. they usually end up being the more famous since there seen more.
