I should point out that several top tech innovators were trained, not in traditional boring schools, but in Montessori. These schools emphasize the Learn By Doing model without grades or tests.

Look at the minds produced: Larry Page and Sergei Brin of Google, Amazon's Jeff Bezos, Wikipedia's Jimmy Wales, etc.
