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.

It's interesting to see the lament of each generation overwhelmed by the next new tool. I can show you passages from scholars of Germany in the 1480s lamenting the fact that they are overloaded with all this stuff to read because of the printing press.

I think it was Samuel Johnson who said, "There are two kinds of information in this world: that what you know and that what you know where to get." The tools help the latter, and that's what keeps us from going nuts. The sense of overload comes from the gap between that sudden jump in volume (of information) and the tools we have to make sense of it.

I'm not sure the notion of employee or job is going to survive the transition over the next couple of decades. The very notion of a fulltime job will seem as quaint in 20 years as the notion of someone getting a gold watch at their retirement in the 1950s.

The difference between our collective generation and your generation (differentiating the reporters from the students) is that we poured our souls out on paper that got easily yellowed and lost. The danger is that many of your friends (nodding at the students) are putting intimate ideas in cyberspace journals. So when today's 15-year-old is 40, some friend is going to drag out all of that idiotic stuff at their class reunion.

I live on a canyon at the edge of San Mateo. We are fortunate to have lots of suburban wildlife as our neighbors, though I kind of wish the rattlesnakes would stop curling up by our back door.

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