- He was fortunate enough to be a founder of one of the dot-com boom's most successful companies, starting him out as an Insanely Rich Individual.
- He has a smart mind for business, when he uses it.
- He has a knack for envisioning products that aren't just incremental steps forward from what's out there, but multiple steps forward, and then unifying people smarter than him into implementing that vision (the "Steve Jobs effect").
He didn't invent rockets that can land themselves. He had the idea, figured out the business plan, and funded it with his piles of money. That's not nothing, but it doesn't make him Our Lord and Savior. And even if it did, that doesn't give someone a free pass on being a jerk to others (he hasn't been that big of a jerk, as billionaires go, but the principle remains).
