Three types of job in a robotic future?

According to a post on Twitter, there will only be three types of job in the future: People who tell the robots what to do; People who are told what to do by the robots; and Robot repair.

Maybe so, but it’s a variation on a similar theme from the 1980s, when automation was seen to be a threat to a number of industries. Then, the story went along the lines of there only being the need for three things in a factory: automated machinery; a man; and a dog.

The purpose of the man was to feed the dog and the purpose of the dog was to keep the man away from the machinery.
