Bill Gates warns of AI's impact on jobs: The world may undergo a 20-year turbulent transition, and we need to start preparing now.

"Artificial intelligence and robots may eventually be able to create a society of sufficient abundance, allowing people to shorten the workweek or even retire early, but before that, the world may have to go through a turbulent transition period of about 20 years." Bill Gates recently said this in a media interview regarding the potential employment impact of artificial intelligence. "When I talk with leaders of various countries, I always say: please start thinking seriously about this issue now, because you may be underestimating it."
