The robots taking jobs thing is wildly overblown as is the high level of training “required” to work on them.
I’m a high school drop out and I learned to program and maintain a bank of robotic painters as well as running the rest of the paint room. A Fanuc rep would come in for software upgrades but they were under contract to do that anyway.
High school dropout is not necessarily correlated with low IQ.
The problem with retraining people is not their level of formal education, it’s their level of intelligence.
Education can be acquired. Intelligence cannot be. It is quite probably largely fixed at birth, and is certainly fixed by the time one becomes an adult.
