Good luck-- I share your view that coming up with better ways of playing zero-sum games is not the way to make the world a better place.
The fact that this statement is coming from the 'lead developer' of Bitcoin does NOT make me feel good about the future of the Bitcoin project. Shows a complete ignorance of markets and economics. Epic epic epic fail.

But don't worry, bitcon doesn't need its developper to understand economics to keep its value, as long as it keeps its original creator's properties (and it will).
Or maybe he understands it better than most. I suspect Gavin feels a bit like he's part of The Manhattan Project.
