...British inventions -- the gas turbine and jet engine, railways, penicillin, radar -- had become the cornerstones of several key American industries. The British invented, the Americans profited. Why? It's not because Americans are sleazy opportunists. Instead, these American visionaries were bold enough to think they could change the world and pragmatic enough to use whatever technology and information existed.
BTW, add "electronic, programmable, digital computers" to that list, would ya?
