When money's on the line, everyone hedges.
Yes, I think even in some crazy distant future utopia, humans will still often want to interact with humans for things, and even to pay them for some services. Tasks that include speaking one-on-one and producing works of art will always retain some value to people, even when AIs can one day trivially produce things which most humans find aesthetically superior to anything a human could ever produce alone. People will seek other things out of art beyond aesthetics, like expressions of human emotion.
Humans will enjoy and seek out human contact. This is not surprising. Just, for economy-impacting labor, I think it's almost all going to be machines, with very few humans playing any role. Even an oversight or accountability role. I think there's a 95% chance of it by 2100 and an 85% chance of it by 2066, conditional on no laws that forbid replacing jobs with AI.
I could point out that that as far as economy-impacting labor goes, it's almost all machines already today. At least in the developed world, few people do any kind of work that isn't at least partially mechanized. You don't see it because lawnmowers and spreadsheets are "normal" machines in your mind.
You're making the "this time it's different" case that AI will be categorically different from every other form of labor-saving automation that's come before it. I work with these models every day and I'm not buying it.
