Back in the 1980s, when the internet was only available to a small number of pioneers, I was often confronted by people who feared that the strange technologies I was working on, like virtual reality, might unleash the demons of human nature. For instance, would people become addicted to virtual reality as if it were a drug? Would they become trapped in it, unable to escape back to the physical world where the rest of us live? Some of the questions were silly, and others were prescient.

A file-sharing service and a hedge fund are essentially the same things. In both cases, there's this idea that whoever has the biggest computer can analyze everyone else to their advantage and concentrate wealth and power. It's shrinking the overall economy. I think it's the mistake of our age.

Advertisers are not thinking radically enough - they look for technology to lead instead of trying the neuroscience approach and thinking about what parts of the brain haven't been activated before. These new experiences bring new capabilities to the brain.

In history, in most cultures, and at most points in time, if you want to find the most advanced technologies, you can look principally in two places. One is weapons and the other is musical instruments. My hypothesis is that instruments are usually ahead of weapons. In fact, I think you can find many examples of instruments being predecessors of weapons and very few in the reverse.

The network by itself is meaningless. Only the people were ever meaningful.

Digital technologies are setting down the new grooves of how people live, how we do business, how we do everything--and they're doing it according to the expectations of foolish utopian scenarios. We want free online experiences so badly that we are happy to not be paid for information that comes from us now or ever. That sensibility also implies that the more dominant information becomes in our economy, the less most of us will be worth.

The most effective young Facebook users, however -- the ones who will probably be winners if Facebook turns out to be a model of the future they will inhabit as adults -- are the ones who create successful online fictions about themselves.
