Eric Schmidt is one of the leading visionaries of our time. He has taken Google from a small start-up to one of the world’s most influential companies. In this conversation with Bryan Appleyard from May 2013, he sets out the themes of his new book 'The New Digital Age: Reshaping the Future of People, Nations and Business', which he has co-authored with Jared Cohen, director of Google Ideas. These include:- new technologies that will change lives: information systems that increase productivity, thought-controlled motion technology that will revolutionise medical procedures, and near-perfect translation systems that will allow us to communicate with anyone on the planet.- the threat to privacy and security: how much of these will we have to sacrifice to be part of the new digital age- the politics of the hyperconnected world: who will be more powerful, the citizen or the state- the threat of cyberterrorism: will technology increase or undermine our security
