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."

It turns out it takes 30 years for a new idea to seep into the culture. Technology does not drive change. It is our collective response to the options and opportunities presented by technology that drives change.

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.

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.

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.

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.

Responding to climate change will become the obsession of the next decade in much the same way terrorism was this decade's obsession.
