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.

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

I think companies over the last 10 years have done a very bad job of explaining to their employees what the intrinsic risks are. All I know is, if you wait until you let the employee go to deal with the issue of how do you communicate to the employee about being let go, it's too late to do anything.

The arrival of television established a mass-media order that dominated the last 50 years. This is a personal media revolution. The distinction between the old order and the new order is very important. Television delivered the world to our living room. In the old media, all we could do was press our noses against the glass and watch.

The Web is a compelling new medium being put to all kinds of uses, by everyone from banks to Cub Scouts to flying saucer cults. That said, it can also be a powerful folly amplifier.

It turns out it takes 30 years for a new idea to seep into the culture. Technology does not drive change. It is our collective response to the options and opportunities presented by technology that drives change.

You don't want to rely on an expert to tell you what lies ahead.
