Re: Robots = more jobs
That's not how automation works, and has never been how automation works.
If as many jobs are created to repair the robots as the robots destroy, then there is no sane reason to use the robots. It's just more training of human beings and more capital outlay required for the exact same results.
If fewer jobs are created to repair the robots than are displaced by the robots, then it's worth using them but lots of people need to find new jobs.
The tractor did not cause the 70% of humanity that were no longer required on the farm to go off and get jobs as tractor mechanics.
