This is just repeating the fallacy that the person being replaced is going to be the blue-collar worker.
But it isn't...it's the office knowledge worker. Anyone cruising in the middle bucket where you don't do creative research, but you do sit in front of a computer. AI is coming for those groups.
The blue collar worker? They'll be fine for decades. Anyone who gets out there and manipulates the physical environment, won't be replaced any time soon.
