Change is easy, except for the changed part.

The protean nature of the computer is such that it can act like a machine or like a language to be shaped and exploited.

In our society we have hard nerds and soft nerds. The hard nerds are the ones who used to have the slide rules at their belt; now they have calculators. The soft nerds are the ones who get violently ill whenever anybody mentions an integral sign.

The computer is simply an instrument whose music is ideas.

Understanding- -like civilization, happiness, music, science and a host of other great endeavors--is not a state of being, but a manner of traveling. This great road has no final destination. The journey itself is the reward.

The only way you can predict the future is to build it.

When the Mac first came out, Newsweek asked me what I [thought] of it. I said: Well, it's the first personal computer worth criticizing. So at the end of the presentation, Steve came up to me and said: Is the iPhone worth criticizing? And I said: Make the screen five inches by eight inches, and you'll rule the world.
