This is a discussion Jimmy Carter wanted to have when computers were just becoming mainstream --- the idea was the taxes on the sales of computers would be used to fund worker re-training --- cue old news stories about the compositor unions bargaining for sinecures and the last compositor retiring after decades of punching in and sitting in the breakroom all day.
LLMs and robotics look to be the first mainstream technological development in a long while which not only reduces the number of workers needed, but also doesn't have a commensurate increasing of the size of the economy in terms of increased wages through efficiency and profits being paid as wages --- instead, it is the concentration of profits by those who own the means of production as Karl Marx warned about and the Luddites feared.
If less work is needed to keep society running, why not have a reduction in the work week, and either pay folks overtime (in keeping with the increased efficiencies/profits) or have more workers (to reflect the added efficiency and spread out the workload).
Or, perhaps it's time for universal basic income?
