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."

Think about reading: Today, parents would love it if their kids read books more because the parents understand the books. Just over 100 years ago, parents were upset because their kids were reading dime-store novels. Parents would say, "I don't want you inside reading anymore. Get outside and play." I guarantee you, in 50 years or so, parents are going to say, "You're not going outside to play until you finish that video game."

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.

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.
