He might have beaten Al Gore to inventing the internet.
Hitler was a technical illiterate fascinated by the fruits of technology he never really understood and upon which he made sweeping generalizations and pronouncements, while loathing and envying its creators. If he were alive today and living in Wisconsin, he’d be on the liberal arts faculty of a third rate community college and a Democratic Party activist.
There are practical reasons railroads are the size they are. Hitler seemed to have a preoccupation with giganticism, perhaps to compensate for personal deficiencies. There is a difference between being a visionary (Steve Jobs) and a meglomanica ( A. Hitler, B. Obama).
That reminds me of the Dilbert cartoon where the boss says, “Forget the technical mumbo jumbo. Just tell me if it works.”
