I think one of the things that really separates us from the high 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 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 human on a bicycle blew the condor away, completely off the top of the charts. 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.
