And it's not just low skill manufacturing jobs that will go away. Lawyers and doctors will likely have large parts of their jobs replaced. While I doubt all lawyers and doctors are replaced, we won't need nearly as many. In the case of doctors that might actually improved things since we don't have nearly enough of them. I think the Covid shutdowns showed that we can't just replace teachers with AI. Most kids just won't do anything when they are at home. I'm even skeptical of a hybrid version where a single teacher monitors a hundred students.
But it is coming and to maintain civil order they will need to do something. That said, I think we are a long, long time away from trade skill jobs being replaced, like electricians, plumbers, and mechanics. Unless you are going to be an engineer making sure the AI runs properly or one of the corporate elites (you likely will have to be born into that), then learning a trade skill might actually be the easiest way to make an income higher than the universal basic income being provided. I suppose being a politician will still be available but it won't be much better work than being a prostitute.
