TEN years ago, a piece of software called Napster taught us that scarcity is no longer a law of nature. The physics of our universe would allow everyone with access to a networked computer to enjoy, for free, every song, every film, every book, every piece of research, every computer program, every last thing that could be made out of digital ones and zeros. The question became not, will nature allow it, but will our legal and economic system ever allow it?
The irony of the battle between advocates of abundance and advocates of scarcity is that both sides are right. It makes no sense to limit and control access now we have technologies to give information to everyone. But it is also foolish to pretend we do not need incentives to help produce and publish that information.
