Don't leave hold of your common sense. Think about what you're doing and how the technology can enhance it. Don't think about technology first.

The inner sort of consumer identity got the best of people. And everybody just wants things for free. And that's created this strange kind of cheapness to everything, where everything becomes throwaway. And people, I think, have started to undervalue things, maybe because there's too much, maybe because it's too easy to make, but I think mostly just because, somehow, that's the pattern that got set. And I think that's regrettable.

The Internet is an incredible business tool. First of all, the Internet/the cell phone - the cell phone is just another way to get at it - I think is having a huge impact in Africa most particularly, where it enables people - suddenly, they know crop prices. They can communicate. It makes their lives more efficient.

Encryption...is a powerful defensive weapon for free people. It offers a technical guarantee of privacy, regardless of who is running the government... It's hard to think of a more powerful, less dangerous tool for liberty.

No system in the world is so well-designed that it can't grow stale, rigid, or corrupted by those who benefit most from it.

I think I have the right to know what Steve Forbes paid in taxes - I don't think there should be a law. I think there should be a presumption. I wouldn't vote for a guy who wouldn't reveal what he paid in taxes. That kind of thing.
