If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, it's likely that no personal computer would have them.

When we started off we didn't know how to spell software.

I'm sorry, it's true. Having children really changes your view on these things. We're born, we live for a brief instant, and we die. It's been happening for a long time. Technology is not changing it much - if at all.

The system is that there is no system. That doesn't mean we don't have process. Apple is a very disciplined company, and we have great processes. But that's not what it's about. Process makes you more efficient ... But innovation comes from people meeting up in the hallways or calling each other at 10:30 at night with a new idea, or because they realized something that shoots holes in how we've been thinking about a problem. It's ad hoc meetings of six people called by someone who thinks he has figured out the coolest new thing ever and who wants to know what other people think of his idea.

A lot of people in our industry haven't had very diverse experiences. So they don't have enough dots to connect, and they end up with very linear solutions without a broad perspective on the problem. The broader one's understanding of the human experience, the better design we will have.

The engineering is long gone in most PC companies. In the consumer electronics companies, they don't understand the software parts of it. And so you really can't make the products that you can make at Apple anywhere else right now. Apple's the only company that has everything under one roof.

the people who are crazy enough to think they can change the world are the ones who do.
