Well, he’s got emerald-mine money to throw at problems, and he’s been lucky. Money and luck are a potent combination, and can stand in for actual talent and skill in a lot of cases.

He’s also had a good eye for tech investments in the past, though he seems to have lost that recently. For example, he co-founded OpenAI. (Sold all his stake in it to Microsoft before it hit the big-time, though.)

So… luck, money, and a history of investing in or founding tech companies that become at least moderately successful off the talents of others. Of course that’s going to give him an enormous ego and make him think everything he touches turns to gold.
