If you look at the last 150 years, about every 30 years or so, a new scientific discipline emerges that starts spinning out technologies and capturing people's imaginations. Go back to 1900: That industry was chemistry. People had chemistry sets. In the 1930s, it was the rise of physics and physicists. They build on each other. Chemists laid the experimental understanding for the physicists to build their theories. It was three physicists who invented the transistor in 1947. That started the information revolution. Today, kids get computers.

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?

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."

The best way to let people go is to let them know when they're hired that it's an uncertain environment and that their job is always at risk and even if you let them go, it's not that you don't love them.

Before the iPhone, cyberspace was something you went to your desk to visit. Now cyberspace is something you carry in your pocket.

There is reason to be scared. Look at what has happened with fundamentalism - this is a reaction against modernity. It happens to be cloaked in religion, but these are people saying enough is enough. It's happened again and again through history. The good news is that modernism has always won.

I don't think information overload is a function of the volume of information. It's a derivative of the volume of information plus the sense-making tools you have.
