I can remember back in the post war days and the birth of robotics in the automobile industry; people used to say "robots will take away our jobs". Those who supported the development and implementation of robots countered with "humans will still be needed to service the robots". Half a century later, have robots eliminated jobs as much as the early critics claimed? I guess unemployment figures from 50 years back to the present might give some clue, but how accurate would it be?
In a TV episode of "How it's Made", they toured a factory making LEGO. They said the factory was 100% automated and 150 workers were replaced by robots. They didn't say what happened to the 150 replaced jobs, whether they were reassigned to other positions or let go.
