Robots and smart machines are changing the world we live in - in rich countries, some supermarkets are already offering entirely automated check-outs, and call centres are increasingly using talking robots. But how far are we humans willing to put up with dealing with machines, the lack of personal interaction? And how smart are these robots really? We hear from Peter Lee, senior corporate vice president and the head of Microsoft Research. We also talk to Kevin Surace of AppVance, an analyst of future trends in technology, who raises the possibility of social upheaval come the day, not so far in the future he reckons, when robots become cleverer than we are.
