“I think that one of the things that 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. Humans came in with a rather unimpressive showing of about a third of the way down the list – it was not too proud of a showing for the crown of creation. So that didn’t look so good. But then someone 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. It’s the most remarkable tool that we’ve ever come up with. It’s a bicycle for our minds.”
