I wonder who's gonna develop this system and how will they manage it? Sometimes even domains that appear simple end up reaching unexpected complexity, and this Simulator is already set to handle enormous complexity and massive data. I can see the value in being an open source of cross-referenced data that would then be digested by proper research. Though as a simulator, I'm not so sure. Not to mention the bugs. I doubt this complex undertaking will be bug free, and being not so, can the outcome be reliable? Who will debug the predications? I think, as a rule, that we should not leave to computation what we ourselves cannot fathom. If we had a grand understanding on human behavior, individual and collective, then maybe this could be done, but how can we determine the correctness of a program that does something we can't, right now, fully comprehend? I think there's much more value in trying to procure all this data in order to enhance understanding of social behavior in face of historical data.
