And has meant that some professions are basically dead and fewer people are in lots of jobs. The folks that lose jobs aren't generally qualified for the jobs that opened and aren't always even located in the same country.

…Yes? Someone needs to design the robots, build the robots, administer and direct the robots, repair and maintain the robots, evaluate the performance of and improve upon the existing design of the robots… not to mention write the software that controls the robots in the first place, design the UI that users use to interface with the robots…

And the 1,000 people, who are replaced by 100 robot workers, are out of a job while the robot owners just get richer.

The robot revolution only benefits the people at the very top of the social stratum.

I’d guessing that the robot designers and warehouse workers are not going to be the same people.

This isn't special to robotics, though. Folks making software are generally not the folks that lost their jobs because of software either.

Pre WW2 the USA had skid rows and flop houses full of men who didn't make the cut to the new industrialized economy. People literally rented a rope to lean on for the night. WW2 changed things for the US where that was no longer a common thing.

People fear that we are heading back into that, with no plan other than 'things turned out fine last time this happened' ignoring the, you know, skid row, flop houses, etc and no idea what the magic jobfairy will bring us to be these new, magically appearing 'jobs to come'.

presumably if they become as popular as software, they would...

Yes.
