與史蒂芬·喬布斯一起學(xué)英語(yǔ)視頻教程(高級(jí)):3_Steve Jobs Computers Are Like Bicycles for Our Minds

I think one of the things that really separates us from the high primates is that we're tool builders.

And 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.

So, that didn't look so good, but then somebody in Scientific American...

...had the insight to test the efficiency of locomotion for a man on a bicycle.

And a man on a bicycle or 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.

And it's the equivalent of a bicycle for our minds.
