Well, since we're talking about it, maybe you're down to answer a question I've always wondered about: money into the hundred millions, let alone billions, is for me an unfathomable amount of capital for one person to wield. I've always thought, if I ever had that kind of power to swing around, I'd spend it all trying to solve every problem I could get my hands on, until there was nothing left but my retirement fund (which could be 10 million and still let me spend hundreds of millions while retiring in permanent wealthy comfort). Hunger in specific areas, housing crises, underfunded education, across the world many issues that, at least locally, one individual with that kind of money could, so far as I can tell, independently resolve.
Why aren't the ultra rich doing it? You seem to have a more philanthropic mind than most, you're doing this cool project and nobody can deny your FOSS contributions. But even you are still holding onto keeping that count into the hundreds rather than the tens - is there some quality of life aspect hidden to us that's just really difficult to imagine giving up or something? Yacht life? Private flights? Chumming it up with Gabe and Zuck?
Becoming that wealthy won't happen to me but if it did, what would change about me that'd make me not want to spend it all anymore?
It's such an interesting phenomenon that so many ultra rich people are essentially just hoarding wealth beyond what they should reasonably be able to even have use of in multiple generations. Worse, some of them simply cannot seem to get enough and will literally commit crimes and/or do indisputably morally wrong things to get even more.
I would personally never ask anyone this, and I wouldn't expect anyone who could answer it to actually answer it, but I think what komali2 asked is one of the most interesting questions out there.
You did mention something I didn't think of which is lifetimes, I guess if someone wanted to guarantee an ultra wealthy lifestyle for all generations of their kids and grandkids forever, that would be a reason to hoard wealth into the hundreds of millions.
