[Alan Turing] also had a trait, so common among innovators, that was charmingly described by his biographer Andrew Hodges: “Alan was slow to learn that indistinct line that separated initiative from disobedience.”
But the main lesson to draw from the birth of computers is that innovation is usually a group effort, involving collaboration between visionaries and engineers and that creativity comes from drawing on many sources. Only in story books do inventions come like a thunderbolt, or a lightbulb popping out of the head of a lone individual in a basement or garret or garage.
