I think one of the things that really separates us from the higher primates is that we’re tool builders. I read a study that measured the efficiency of locomotion for various species on the planet. The Condor used the least amount of energy to move a kilometer. And humans came in with a rather unimpressive showing about a third of the way down the list. It was not too proud of a showing for the crown of creation.
That didn’t look so good. But then, somebody at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle. And a man on a bicycle completely blew the Condor away, completely off the top of the chart. And that’s what a computer is to me. What a computer is to me, is it’s the most remarkable tool that we’ve ever come up with. It’s the equivalent of a bicycle for our minds.Steve Jobs
