More information and more communications foster world peace and understanding. But connecting extremist nut cases together on the Web - whatever flavor extremism they are - is a really bad thing. More information may not be a good thing, either.

As recently as the '70s, people were forced to see information that they didn't agree with in newspapers and the like. Now there is so much information you really can build your own walled garden that just has the stuff that reinforces your view. I think it applies to all of us. People are really going into these separate camps, and that's the big social challenge in this age of too much information. How do we crack that and create a common dialogue?

Sometimes I think we're on this world for three reasons: to be useful, to tell each other stories and to collect stuff. It's the only explanation for eBay. We love to collect stuff, and at least if we're collecting stuff in cyberspace we're not deforesting the Sierra Nevada.

People were touchingly naive at the dawn of the Internet revolution when they said the Internet will route around censorship the way it routes around damage. With any revolution, the establishment catches up and figures out how to screw it up. The answer is to keep technology advancing fast enough so that those who would try to control it can't. It's up to people to defend what they care about. We shouldn't be complacent that this stuff is going to be a force for good.

Take cyberspace as an example. We had this wonderful utopian vision of a new home for the mind. What we've reaped isn't cyberspace. It's cyberbia. It's this vast, bland wasteland of vulgar people and trivial ideas and pictures of half-naked starlets. But despite all the uncertainty, has there ever been a more fascinating moment to be alive?

We invent our technologies and then we turn around and use our technologies to reinvent ourselves as individuals, communities and cultures.

The best way to let people go is to let them know when they're hired that it's an uncertain environment and that their job is always at risk and even if you let them go, it's not that you don't love them.
