I think GP's point was _why_ they were building what they were building. Gate's was just doing work in his field, whereas Zuckerberg was working towards his ideology. Gate's didn't have the strong sentiment towards his business that Zuckerberg did/does.

Well ZuckerBerg is still in his early 30s, it's probably too early to say that he will stay at Facebook forever. People change with age as well, no matter what he may be thinking about currently.

Who knows, maybe some day he'll change his mind about people over 30 being too old to work for him.
