Whether they're trying to program the heating or organise photos online, machines never seem to work properly. So I share Microsoft's scepticism that artificial intelligence (AI) is a threat to us.
AI is all about making a machine 'think' like a person. We've often seen it go wrong in films, though that doesn't stop people researching it further.
But AI can be useful - when trying to automate a car for example, or by acting as your voice-controlled personal assistant. I think we should play down the dangers of AI.
