It was one of those sort of apocalyptic moments. I remember within ten minutes of seeing the graphical user interface stuff, just knowing that every computer would work this way someday. It was so obvious once you saw it. It didn't require tremendous intellect. It was so clear.

So [Polaroid's Dr. Edwin] Land, at 75, went off to spend the remainder of his life doing pure science, trying to crack the code of color vision. The man is a national treasure. I don't understand why people like that can't be held up as models: This is the most incredible thing to be - not an astronaut, not a football player - but this.

Innovation distinguishes between a leader and a follower.

When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of the bibles of my generation. It was created by a fellow named Stewart Brand not far from here in Menlo Park, and he brought it to life with his poetic touch. This was in the late 1960's, before personal computers and desktop publishing, so it was all made with typewriters, scissors, and polaroid cameras. It was sort of like Google in paperback form, 35 years before Google came along: it was idealistic, and overflowing with neat tools and great notions.

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.
