The value of a social network is defined not only by who's on it, but by who's excluded.

We do need to rethink privacy. I think we need to fall back on (former Supreme Court Justice) Felix Frankfurter's definition of privacy which is, "Privacy is the right to be left alone."

Every day huge amounts of information break off like icebergs and melt away. What worries me is that much information in electronic form is never reduced to paper. Some people have described this as being on the edge of a digital Dark Age and fear we may commit a massive act of amnesia.

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.

This new economy that's just emerged has a new central economic actor. It's not the worker, the person who produces, nor the person who consumes, the purchaser. It's a new actor that does both things at the same time, call them a creator. They both create and consume in the same single act, and we're just beginning to see the shape of this new economy and it changes not just the economy itself, it's going to change the whole nature of the work relationship.

The thing I see happening is that there's a real compression between generations. There used to be about 20 years difference (in technology use). Now you talk to 15-year-old kids and their 9-year-old brother or sister is using stuff that they don't understand.

I've actually tried not to call myself a futurist for the last 25 years. I prefer "forecaster," but people call me a futurist, and it doesn't really bother me.
