When I lived in Japan in the 1980s, I once was mistaken for Paul Newman, and I didn't have much more hair than I do now. My first reaction was that staying in Japan might be good for my social life.

Every new thing upsets people.

It drives the dad nuts, but he can't complain because the kid's a 4.1 (GPA) student.

Never mistake a clear view for a short distance.

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.

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

Digital technology is the solvent leaching the glue out of all of our traditional institutions.
