Terminator-style autonomous lethal weapons, which can make their own decisions about when to kill, are closer to becoming reality than you may realise. How worried should we be? Noel Sharkey, a professor of artificial intelligence, tells presenter Ed Butler why he thinks the world needs to take action now to head off this imminent technological threat. And he's not the only one. A host of top internet entrepreneurs share his concern, including Jaan Tallinn, founder of Skype. And if that isn't enough to have you running for the hills, Jeremy Wagstaff of Reuters tells us why he thinks soon even our own kids' toys could be turned against us.
