 Well good morning to all of you. I hope you are bright and awake after having a fun evening out in that city yesterday. My name is Geoff Mulgan. I'm from the UK's National Endowment for Science Technology in the Arts and I have the job of traffic policeman this morning as we try to cover quite a lot of ground with a wonderful array of luminaries around this table. What we're going to talk about for the next hour and a half is the relationship between the city, technology and creativity. And it's a very complicated set of relationships which many people have got wrong over the last hundred years. Many generations of futurists predicted the end of the workplace, the end of the school, the end of the university campus and so far at least have turned out to be completely wrong. We've seen ever greater concentrations of creativity in particular places and even the highest technology industries like aerospace or programming that seem to depend on a deep craft which resides in particular places and human interactions between people. Again, contrary to most expectations of the past. We will explore a little bit, I hope, some of the relationships between productivity and fun. Is there actually a relationship between urban prosperity and fun or is in fact Silicon Valley a slightly better signal which is not known for its cultural excitements but seems to do pretty well in other respects. To kick us off we have Richard Sennett who you will all know who's given a hint as to what he's about to say in the title of his talk. Richard, over to you.
