Bicycle of the Human mind (excerpt from Jobs interview)

Moderator: I want to know what Steve Jobs is passionate about, what motivates him?

Steve Jobs: When I was a child, I read an article in Scientific American that contrasted the movement rate of various species on earth, such as bears, orangutans, raccoons, birds, fish, and, of course, humans-counting the calories they consumed per kilometer of movement, the Vulture won, and it moved most efficiently. As the universe of mankind, ranked in the penultimate. But the magazine specifically measured the rate of human cycling. The result was to leave the vultures far behind, ahead of the rankings.

This article impressed me deeply that human beings are good at inventing tools and tools that give us wonderful abilities . Apple used to have an advertisement: The computer is the bicycle of the mind, I firmly believe that if someone looks back on human history in the future, the computer will be the greatest invention of mankind. I feel fortunate to be able to participate in this invention in Silicon Valley. This is like drawing geometric vectors. At first near misses, the result will be great difference. I think we are just starting out, if we find the right direction, we will be very smooth. We have tried several times and the results are very satisfying.

I don't think good colleagues work for computers. They work because computers are the best medium you can have to convey some kind of emotion , and they are eager to share

I can't do it, let the computer do it!! Programming Changes the World
