The notion of retraining implies a waiting pool of unfilled jobs. The only industries in the US that are chronically understaffed and desperate for talent are construction and unskilled agricultural labor, neither of which (separately or together) are prepared to absorb the roughly 22 million individuals who work in the service industry in the US. You want automation, you then also have to choose between luxury space communism or open air refugee camps and massive civil unrest.
I don’t even know if I was being sarcastic, hahaha. I mean I was playing with the fact that obviously the latter is a terrible pick, but I’m really worried that we won’t so much pick it as default into it.
