When the Industrial Revolution brought mechanization to agriculture, menial farm laborers became menial factory workers. And then when the factories moved overseas, the menial factory workers became menial service sector workers, flipping hamburgers and stocking the shelves at Walmart.
The Robot Revolution will be different than the Industrial Revolution, because it's not going to simply be a matter of replacing certain jobs. Robots will be capable of doing any menial job that a human could do. Thus people who are not smart enough to do something more than just menial tasks will become economically worthless and unable to find any job at any wage.
How will society react to this? People think we live in a welfare state today, but in fact welfare is not handed out to able bodied men, only to old people and women with children.
Will there be an uprising of unemployable dumb people who rampage and destroy all the robots they can find?
Today our politicians act as if all people are born with equal intelligence, and unequal outcomes in life are blamed on bad schools. Will the Robot Revolution finally wake people up to the fact that people are born with differing levels of genetic intelligence, and those with too little genetic intelligence are now worthless to society because of robots?
Will eugenics, a taboo topic today, make a resurgence, because people will decide that for the good of society those who are unable to contribute anything at all shouldn't be allowed to pass their genes on to future generations?
