> I'll bet the Maginot Line was pretty cool technology in its day as well. Definitely. Hidden tunnels with high speed trains to bring ammunition and personnel at any point in no time; hidden turrets in the forest that emerge from the ground; dragon teeth and minefields prevent tanks from going through. Unfortunately big brass love big weapons, big bombers, big ships, big guns; never mind if they're useless nowadays in a world of guerilla and IEDs. The future is not the F22, it's a slow and cheap remote controlled drone with a propeller.
