I think seeking perfection in human affairs is a perfect way to destroy them.

Every time we give a musician the advice to give away the music and sell the T-shirt, we're saying, "Don't make your living in this more elevated way. Instead, reverse this social progress, and choose a more physical way to make a living." We're sending them to peasanthood, very much like the Maoists have.

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.

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.

We should treat computers as fancy telephones, whose purpose is to connect people.... As long as we remember that we ourselves are the source of our value, our creativity, our sense of reality, then all of our work with computers will be worthwhile and beautiful.

I'd much rather see a world where, when you make some quirky comment on a blog or news story or you upload a video clip, instead of just a moment of fame for your pseudonym, you'll get 50 bucks. The first time that happens, you'll realise that you're a full-class citizen. You have the potential to make money from the system.

In fact, one reason I am interested in developing things in virtual reality is that they're so fascinating. I can come up with problems that are harder than warfare to take up people's time.
