On this note, even if LLMs or "AGI" make businesses more profitable by improving margins and allowing them to cut labor costs, you eventually have to balance it out somehow - all those people who've lost jobs are competing for a smaller number of available jobs, and the people who can't find jobs will either need to be supported by taxpayer dollars or die in poverty.
People talk about UBI as a solution for this but the money for UBI has to come from somewhere. Are corporations going to voluntarily pay a new tax to support UBI?
