When you advance a frontier and you do tomorrow what's never been done today, you have to innovate to make that happen. You become an innovation culture. When I grew up, every time I turned around it was, "Oh, here's the longest bridge or the deepest tunnel or the fastest airplane." And I originally thought that was just kind of like a pissing contest with men with too much testosterone. And then I realized that to make the tallest building you have to innovate. To make the fastest train you have to design the train in a way that it's never been designed before.

The theory of evolution, like the theory of gravity, is a scientific fact.

Let's create a World's Fair that captures everybody's visions of tomorrow together and let's celebrate that vision. Let's have articles on it with illustrators imagining how we'd be living differently.

There are no wild, seedless watermelons. There's no wild cows... You list all the fruit, and all the vegetables, and ask yourself, is there a wild counterpart to this? If there is, it's not as large, it's not as sweet, it's not as juicy, and it has way more seeds in it.

I remain unconvinced that anything other than rapid decomposition is the fate of my body and mind after death.
