Interesting idea to be sure. What makes it particularly interesting though is the lengthy, often apparently somewhat expert (or at least well-informed) explanations of each bet. Good examples include "No self-aware computers by 2050" and "no explanation for the shroud of Turin by 2012". Great discussion boards, too. Far too much stuff for me to dive into, much as I'd like to. But a great place to wander when you're bored, if nothing else. For anyone seriously into these ideas it's a heavenly playground. A large group of serious futurists and predictors, with very well thought out and interesting explanations for their stances. And hey, it all goes to benefit charity in what appears to be a very solidly structured long-term funding arrangement, so you can feel good about it too.
