What? We’re talking about a post-scarcity future and you think someone will be depressed because they don’t get to edit spreadsheets anymore? Poor guy only has infinite opportunity to pursue their limits (or not!) in the area of their choosing…
Do I play hockey with the end-all-be-all of becoming the next Gretzky? Or do I play because I enjoy it and want to push the limits of my mind and meat-suit?
Maybe I'm cynical and have low status friends but when I look around only a minority pursue hobbies with any great dedication or consistency. People pursue careers to project status. When success no longer depends on merit it will devolve to proxies like nepotism, scheming, intrigue etc. We see how such utopias play out in regimes like Soviet Union or North Korea. Your only assets in such places are who you know and even that is very temporary as allegiances are reshuffled with some regularity and woe is you if you bet your fortunes on the wrong one.
