In high school, on the last day of English class, the teacher decided to kill time by asking the class what the future would be like. I raised my hand and said that all jobs would be eliminated and all workers would be replaced by machines. I (quite the high school wit) added that the only job that would still exist would be that of being a contestant on a game show.
In the future as the class saw it, life would not be so bad, though. There would still be a few things for people to do. Work hours could be drastically reduced, though, and we would all make plenty of money, thanks to the advances of automation and government spending.
So far only the elimination of jobs has happened. The rest has turned out to be as likely as the cigarette trees sung about in the big rock candy mountain.
