Yep, that's going to be the main outcome I suspect. The bottom 50% or maybe even 80 to 90% of knowledge workers are going to have to go back to physical work. That too will eventually be automated, but I suspect things like construction work (including the many trades wrapped up therein) will be toward the end of that.
Maybe that's why the current administration is pushing so hard to bring back low end manufacturing.
If you're a SWE, Accountant, Marketer, HR person, etc. put out of work by AI, now you can screw together iPhones for just over minimum wage. And if we run out of those jobs, there's always picking vegetables now that all the migrants are getting deported.
It would not surprise me one bit if the Tech CEOs see things this way.
