Before the industrial revolution, most people were occupied in growing food. After the industrial revolution, most people were occupied making things. If a robot/AI revolution removes making things and the ancillary jobs of distribution and servicing, there isn’t any obvious replacement.
With all this automation and AI, nothing seems to be getting cheaper. Cars, houses, stuff in general keep getting more expensive. The only exception is consumer electronics. You still need money to live.
Paying people to do nothing leads to people who are worth nothing and has failed where it has been tried. Earning your livelihood is key to self-respect and requires an economy with the full mix of jobs that allows everyone something they can do. Unless something shows up to create this economy, the robot/AI revolution will self-destruct against the reality that people without jobs can’t buy the stuff produced by it.
