Tim Cook, speaking at Harlow college in Essex, shared his views on the limits on technology and social media he feels should be imposed on kids. He said: "I don't believe in overuse [of technology]. I'm not a person that says we've achieved success if you're using it all the time," he said. "I don't subscribe to that at all." Even in computer-aided courses, such as graphic design, technology should not dominate, he said. "There are are still concepts that you want to talk about and understand. In a course on literature, do I think you should use technology a lot? Probably not." The 57-year old chief executive, who took the reins at Apple after the death of Steve Jobs in 2011, said the company cared deeply about children outside the classroom. "I don't have a kid, but I have a nephew that I put some boundaries on. There are some things that I won't allow; I don't want them on a social network."
