It’s not a new social construct. It’s a very old one: a thin layer of rich people, and a large number of poor people fighting to survive because they don’t have anything to contribute beyond their own manual labour.
Head out of the developed world and you can see this type of society everywhere.
This meme of AI -> upheaval -> basic income utopia has got to die. It’s wishful thinking. It’s “clean coal” for programmers.
