I say this to everyone who will listen. The danger from AI is not a Terminator situation. It's economists, billionaires, and c-suite execs who don't know shit about fuck, that will push to replace their workforce with AI. In the short term it'll even work too for a lot of companies, which is the sad part.
As OP said though, long term it's a recipe for failure. If nobody is working then nobody is getting paid and therefore can't buy anything. The billionaire class, however, won't admit that they've fucked themselves until mobs start showing up to strip their houses of copper wire and valuables. We'll be neck deep in civilization collapse at that point.
