If you don't actually have the desire to build, lead, and manage a large organization, this is a terrible idea for technical geniuses. A guy like him will instantly raise $1 billion which means hiring dozens of people, which means tons of interviews, management, performance review, planning, board meetings, etc etc.

It's good that there are avenues today for people to make tens or hundreds of $m in salaried positions at companies so that they don't have to do that stuff to get paid their value if they don't genuinely want to.
