I worry about a society that can remember everything.

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."

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

I think of futurists as people who have a particular attitude about the future. They're advocates for a certain kind of outcome. As a forecaster I am something very different. I am a professional bystander. I have opinions about the future, of course. But my whole posture is to be detached and to identify what I think will happen and not allow my judgments of what should happen to get involved.

It will take a decade or two, but fundamentalism is going to burn itself.

My driving style is alert. As a forecaster, I can't help but think about who else is on the road and how little attention they are paying to their driving.

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