Lead advisor to the WEF, Yuval Noah Harari, call us useless humans and more.

Lead advisor to the World Economic Forum, Yuval Noah Harari, says the biggest problem we face today is what to do with all of the useless people, and says that thinking of the masses as powerful individuals capable of revolutions, is old 19th century philosophy from the masters. He believes it's best to keep us occupied with drugs and computer games, and that Japan is 20 years ahead of us because they live most of their lives in virtual worlds, never leaving their houses.
