I don't think people appreciate the mass disruption of a shift like this happening across so many industries all at the same time. This sort of professional shift works when automation comes for a subset of a single sector, but we're looking at an everywhere all at once situation. How many plumbers are we going to need, exactly?
I also don't think people appreciate the absolute social turmoil that will occur as a result of this because of our complete lack of planning for it.
Afraid you won't have a useful job due to the rapid rise of AI replacing vast amounts of knowledge workers? Get to work building guillotines. You won't be able to sell them for very much but you can make up for it in volume.
To the wealth class: Massive amounts of people don't just quietly disappear when they suddenly can't feed or house their families because they've been automated out of a job.
