A lot of people still have romantic visions of Laverne & Shirley working in the bottling plant and stamping caps on beer bottles. It might look like a good job on TV but it was a dreary way to make a living. Well we have machines that do that now and the Laverne & Shirley's of today are more likely to be creating web content or advising companies on how best to maintain their data in the cloud.
Correct. People will move onto other things and everyone’s standard of living will increase incrementally.
Besides, what’s the alternative? Banning robots?
What percentage of the population do you think is intellectually capable of running a bottle capping machine vs. creating web content or advising companies?
The problem is not the brighter 50%. The jobs you describe, BTW, are probably limited to the top 25%.
The problem is what do the people who could do a fine job on the factory floor but nothing more intellectually demanding do when there are no more factory floors?
