Jeff Weiner, CEO of LinkedIn, said 5 million jobs will be lost by the year 2020 because of advances in technology. Recode reports that Weiner, speaking Tuesday at the Code Enterprise conference, cited factors including artificial intelligence, drones and robots, which he said will be taking 7 million jobs from humans.

Technology will also bring the addition of 2 million jobs, for a net loss of 5 million, Weiner said. He based his conclusion on information from the World Economic Forum.
