I'm not sure that world needs more ballet dancers, but I'm more convinced that we don't need the sort we would get out of public schools. It is absolutely true that the architecture of public education is industrial but so are most of the jobs as 'jobs'. I mean if you want to get 'a job' then public education will get you that.
I'm not sure where he's going with all that. I mean lolcat pictures are creative and enormously popular. We're not missing out. Has there ever been a kind of music you wish you could hear but nobody was making and you couldn't get? Has there ever been a kind of recipe that you wished you could eat but nobody knew? Was there ever a sort of dance move you needed to see but nobody could perform? Exactly what kind of creativity are we lacking for? We obviously have the sort that imagines a planet without humans flourishing in 50 years. Do we need that sort?
I think that the lecturer imagines that human beings are infinite. We are not. Food still tastes good. Sex still feels good. Music still sounds good. Football is still good fun to watch. You don't have to experiment with all that - unless you're a wealthy jaded old fart bouncing around to international conferences telling jokes (about 7 year olds) to a bunch of other wealthy jaded old farts, and their bohemian spoiled children in their obscure fashions. Creativity is natural human expression. We get enough and don't need to be educated about how to be creative.
Art, on the other hand… well that's a different matter.
