I'll give you Jobs, now that he's passed away and we have a lot of the dirt on him. But everyone else, we really don't know about.

Also, (just kind of pointing this out as a relevant factor, not really trying to insult the others), but Steve Jobs is tall and good looking. The guy would have gotten plenty of women with just a guitar and not a nickel to his name. I'm thinking Musk and Gates were very likely not in that league as far as raw attractiveness.
