- he’s technical enough so that he actually understands what he’s doing (unlike a “non-technical cofounder”)

- working on actually inspiring projects (unlike “let’s sell ads” Google, “let’s make rich people richer” finance, “no innovation” Boeing or “Instagram for dogs” bullshit startups)

- he’s rich enough to be able to start his own company with extremely capable people, with less need to please the investors (at least in the short term)

- he’s actually driven, not just money/power-hungry like 99% of billionaires who use their wealth to buy goodwill/influence/art.
