Microsoft founder Bill Gates predicts a future in which humanity will only work three days a week. Gates made the prediction in a new episode of the podcast "What Now?" Gates had only pointed out the risks of artificial intelligence in a post on his blog in July. He wrote that he "does not believe that the impact of AI will be as dramatic as that of the industrial revolution, but it will certainly be as great as the adoption of the PC""If one day you have a society where you only have to work three times a week, that's probably all right," Gates said.
