I love writing software. I write a fair amount of it, and upload it for free. And my experience is that the best way I've found of turning something you love into something you hate is to tie it to being something you have to do, and do by other people's rules. I only started liking writing code again when I moved into management and didn't have to write code for other people anymore. I was able to go back to doing it for pleasure.
So, yeah. In an ideal world, I'd be free to write and publish software, on my time. When I burned myself out, I'd switch to something else; home projects, setting up selfhost servers, maybe build a table. You can't do that when you're doing it for a living. Fuck if I know how we make that happen; I'm not an economist. And I think it's probably another couple of generations away before we could possibly get to a post-scarcity society - even assuming that we don't extinct ourselves, and that the people who could make it happen actually let it rather than greedily using it to enrich themselves.
Automation, clean energy; I think we're close to having the tech for post scarcity. I do believe this: if we freed people from defacto indentured servitude, they might turn into unproductive fat slobs like on Wall•E. Or they might become artists and artisans ushering in a new Renaissance. But I'm optimistic: we won't know until we try, and not trying because we have a low opinion of our fellow man is just callow.
