Mark Zuckerberg warns Harvard graduates machines will take their jobs

Mark Zuckerberg finally has his Harvard degree. The Facebook CEO and famous college dropout left the Ivy League university 12 years ago to found the social network, but he returned Thursday to pick up a honorary doctor of laws degree and drop some wisdom on the class of 2017. In prepared remarks provided to The Washington Post ahead of the speech, Zuckerberg called on his alma mater's newest graduates to tackle major, ambitious "public works" projects that bring together masses of people for the general benefit of society. He noted that many technologies - including some being developed at Facebook - are changing the world and also presenting new challenges. "You're graduating at a time when this is especially important," Zuckerberg said in the prepared remarks.
