I find that most of our most innovative people learned these skills outside of the classroom. They're gifted, you can't teach gift. And I don't think innovation get taught in the classroom either.

Polio Vaccine, Hybrid Cars, Supersonic Jet, iPad, 3D Cinema, High-Yield Corn crops, anti-lock brakes, Space shuttles, Doppler radar, streaming video, earthquake prediction, Blu-Ray, cure for rickets, radiation-therapy, LASIK surgery.

Just a couple innovative things off the top of my head that were invented by people who learned their skills in the classroom, not from instructional youtube clips.
