I think it's more likely he cashes out and becomes another "young prodigy angel/VC/investor".
He doesn't have the work experience to understand the problem domain well enough to build a company to solve it and he doesn't have the life experience to apply what work experience he has had. I'd bet the money I'll net after the lockup on an IPO I'm in that close to 100% of the value of "his" company was built on that bed of VC funds and their connections he lucked into.
He's a cute anecdote for the company's marketing--that's the entire sum of his value. He's not likely to build another company or achieve any further success outside the VC bubble.
