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?

Though I carry enough electronics to get nervous in a lightning storm, I love paper and I always have a Moleskine journal with me to capture notes, conversations and ideas.

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.

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."

Using technology merely to lower operational costs amounts to standing on a whale fishing for minnows. It just allows you to do the old thing more efficiently, where in this moment of deep transformation, it is much more likely that you should be doing something entirely new in an entirely different way.

The most important thing that a company can do in the midst of this economic turmoil is to not lose sight of the long-term perspective. Don't confuse the short-term crises with the long-term trends. Amidst all of these short-term change are some fundamental structural transformations happening in the economy, and the best way to stay in business is to not allow the short-term distractions to cause you to ignore what is happening in the long term.

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.
