My follow up would be, "if AI is doing so many 'menial' jobs, even if AI makes everything cheap, how will unemployed people afford anything?"
Someone recently said there will be "sustainable abundance" but this is magical thinking. There will be abundance for people in one class and death and poverty for people in the other class. But the abundance will not be "sustained" -- it will be fueled by the suffering of the under class.
In the industrial revolution, tractors and machine looms and steam engines did all the old 'menial' jobs. We just invented new jobs that pay better with all the extra wealth created by automation. The middle class grew and quality of life skyrocketed.
It was arguably the best thing to ever happen to the world.
