I remain amused at classic Sci-Fi being reimagined as scientific papers. Authors have warned and celebrated the potentials of AGI on human society for decades if not millennia (if we include deities, gods, and other super-human machinations): we know full well that a post-AGI economy will be hell or paradise solely depending on the underlying civilizational structures when it is birthed into existence (hell if Capital reigns supreme and Nations remain in conflict, paradise if we get our species' collective shit together and consciously shift to a planetary societal mindset for economics and governance).

As for what humans should do when labor can be accomplished via AI? Man, if you're asking yourself that question in 2025, you're kinda late to the party in a lot of ways - and desperately need to read more books. AGI may eliminate the need for human labor in Capital terms, but it does not suddenly eradicate all value of human labor - only the value Capital ascribes to it. It's why, in a post-AGI fictional setting, you see so many more adventurers, artisans, explorers, researchers, engineers, teachers, and other roles often undervalued by Capital but highly valued by humans.

I imagine most humans will simply turn their favorite hobby into their new "profession", as a means to meet other humans and continue growing social bonds. Maybe that means painting full-time, or striking out on a photography journey. Maybe it's opening a retro game "store" to connect with like-minded enthusiasts. Maybe it's running your own museum for local artists and creators, sharing your tastes with other visitors.

A lot of "valueless" work under Capitalism suddenly becomes highly prized in a post-AGI, post-scarcity society. Most humans will figure that out to varying degrees, and the rest will be able to benefit from a wider array of fee-less services. Provided, of course, we begin changing society today to enable that future tomorrow.

You should also read a few more books. Capital doesn't need humans. We are it's temporary vessel.
