Yes. But time is still finite. And a much lesser quantity than "what our hearts desire". To put into a very simplified example: I work 8 hours a day, sleep 8 h

Yes. But time is still finite. And a much lesser quantity than "what our hearts desire". To put into a very simplified example: I work 8 hours a day, sleep 8 hours a day, spend 4 on chores, and 4 on doing what I want. That's 4h/day. Bill Gates has almost immeasurably more money than I have, but he still, at best, gets 16h/day. He can do 4 times as much as I. And I can guarantee you that "things I'd love to do" is significantly more than even 24h/day. I'd assume the same holds for Gates. This is one of the reasons rich people usually have an entire staff running their lives - if you make billions, spending $100k to save 30 minutes a year is actually a reasonable investment. And so, even if he loves to code, he might well not be able to never get to it. (TBF: I'm not saying "poor Bill", I'm sure the other stuff he gets up to is reasonably fun :)
