Adaptation does not require mass retraining into new professions; it happens through task simplification, AI-augmented shallow competence (less qualified people can do more advanced work), partial work, income stacking, and lower subsistence costs. As automation advances, less-automatable sectors (personal services, care, local physical work) see wage pressure rise, consistent with Say’s Law, because yes, what people save at restaurants, is spent instead at barbers, massage therapists, nail technicians, etc.
As for the gains from robotics, they go just as much to workers as to investors. Remember, investors are competing with each other, so they have to keep cutting prices. And that means workers see their wages buy more goods and services, given those goods and services cost less to buy. When wages buy more, that's effectively the opposite of inflation. In inflation-adjusted terms, that equates to a wage hike.
