> it makes me wonder what drives billionaires to keep going. they're probably just bored when they're not working. it really might be as simple as that.

If we're looking at billionaires, it's a very different situation from the rest of the rich.

Billionaires carve out and control portions of civilization. I mean any business or other venture does this to a degree, but when you're working with billions of USD, you're playing a different game entirely. It is about power.
