Google's Executive Chairman Eric Schmidt has challenged young people to give the physical world and human interaction a try - for an hour a day anyway.
Schmidt delivered his message to graduates at Boston University, telling his audience to "Take one hour a day and turn that thing off."
"Take your eyes off that screen and look into the eyes of the person you love", he added. "Have a conversation, a real conversation."
The former company CEO steered clear of recent headline events in the tech world, with many expecting his views on the Facebook IPO, but he did speak of social media's powerful influence on the young generation, saying, "A distinctive feature of your new world is that you can be unique while being completely connected," which, he claimed, was a "fulfilment of the American dream."
Schmidt also commented that, "Some of you are probably tweeting this speech right now". And in a fitting irony, over a dozen members of the audience were indeed commentating live from the ceremony via their accounts.
