I think I've finally figured it out, it's:
1) Start one of these companies secretly knowing it will probably never be profitable
2) Play at being a silicon valley genius for a few years
3) Pay yourself a modest upper-middle class salary while it lasts
4) Have the company declare bankruptcy or sell it
5) Repeat step 1 until you get bored or retire.
The company itself doesn't need to be profitable so long as it's a profitable experience or a write-off for everyone involved.
