And yes, before anyone brings it up, I've read Manna and if you haven't you probably should[0] but I don't think it will be as dystopian or utopian as that. Humanoid robots would obviously replace some of the proxy need but there will still be a lot of things that only a living human can do even if it's just purely for legal and regulatory reasons.
I also think there will be a lot more roles that are purely human in nature and which will have an entirely different set of requirements but that's a different topic.
