The same thing happens with science too. We've been making incremental improvements to the car, the airplane, the motor, the generator, etc but they look and act pretty much the same because students are taught "the way things work" in school instead of examining things fresh. Most E.E. majors have never heard of Tesla (I wish I knew where I read that....) but we need more people like the relatively "unqualified" Wright brothers ect who can truly examine something and innovate in all fields of knowledge.
