I think it's less about "work" and more about reason for being. Work is sort of the easiest, lowest friction way to find that.

Post-scarcity and post-work society takes a formal effort for people to find purpose. It requires that we really try to find things that are valuable and that we enjoy.

But I do not believe we will live, as a society, to see the end of scarcity or jobs. We'll kill ourselves way before we get to that point.
