I feel his $ numbers are shockingly low given his obvious calibre.
Also, he made $4,000 an hour on BCC, so it seems like he's left with a lot! And even so, business come and go all the time. Doing nothing on BCC as it fades from $60k a year to $0 over the course of a decade while doing minimal work on it for the last half of that decade doesn't sound like a bad idea to me at all. Sounds like 'free' money.
(He could do more, but he doesn't have to, which is a great place to be).
