I think one of the big mitigating forces against over-prescribing is students. Students come and look at everything differently. You put them in a lab or expose them to technology, a machine, or an idea, and they're going to turn it on its head in an instant. They'll take us by surprise all the time, so the more they get that chance for hands-on experience, for tossing ideas around....
Paul talked about the multidisciplinary aspect, and I think that's a lot of what those incubators and hubs are all about, getting people from a whole lot of different disciplines, backgrounds, and work experience all together, trading ideas over a cup of coffee or a beer or whatever it is, and that's where those aha moments come from.
