Interesting talk. It's worth putting your feet up for 20 minutes and having a look.
The main thought that struck me is that if he is correct, the state school system is the worst possible way of delivering a creative education. That's because it will always be driven from the top down in a rather mindlessly bureaucratic fashion. If we want schools to "blossom", we need a much wider range of much smaller schools. A school of 100-200 kids is much more likely (in my mind) to be able to succesfully cater to the creative needs of a particular group of children than a monolithic entity of a thousand or more, with teachers and headmasters beholden to managers miles away in shiny offices.
