Plenary Keynote: Van Lindberg, "Intellectual Property and Open Source"
I was up really late, so I missed the first two keynotes and half of this one.
The talk was interesting. He referred to a lot of interesting concepts such as zero sum games, the tragedy of the commons, the free rider problem, the prisoner's dilemma, etc.
He said that open source is not a zero sum game. It can be win win. Furthermore, it doesn't suffer from the prisoner's dilemma because it rewards cooperation and punishes defectors--or at least the GPL does.
He said that as far as economics goes, open source really is revolutionary.
