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?

We've become more and more interrupt-driven. If you have six tasks to do in an hour, you can't just take 60 minutes and divide and have 10 minutes per task. You have 10 minutes per task minus the time required for context-shifting. That will be the next big challenge: figuring out how to fight the distraction-driven mode we're in and stay focused on one thing long enough to get it done.

The curse of cyberspace is that everything we want to preserve will get lost and everything we want to lose will be preserved.

Never mistake a clear view for a short distance.

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.

It's interesting to see the lament of each generation overwhelmed by the next new tool. I can show you passages from scholars of Germany in the 1480s lamenting the fact that they are overloaded with all this stuff to read because of the printing press.

I would say digital technology probably doesn't have much impact on us so far. We've seen photographs of people from when they are alive. We see home movies. We have videotapes now and e-mails. When it's going to get interesting is in massively multiplayer online games where you have avatars (online personas). You could actually create an avatar that's semi-autonomous. It could do things for you while you get off the game to run the rest of your life.
