Living Earth Simulator will simulate the entire world

Its not as crazy as the sensationalist article headline makes it out to be; one excerpt from the "Project Outline" from http://www.futurict.eu/ shows this:
"Most importantly, the FuturICT project will NOT attempt to collect “all the data in the world”, or to represent each individual on the globe by an identical copy in some giant multi-agent simulation, considering private features and preferences of all individuals. Science is the art of abstraction and approximation. Just as maps do not show all the features of our environment, a scientific model is specified such that a particular question can be addressed in the simplest possible way. That is, models are to be problem-specific, and parameters and variables not expected to be relevant for the answer should be neglected."
I don't know much about the details of the specific project; but I think a large degree of scepticism is healthy, when discussing any proposal to build models with very large scope.
People have put a lot of effort into making economic models, but we still aren't much good at predicting the kinds of phenomena that we are interested in, such as the occurrence of crashes. It can be easy to model large scale social phenomena; but modelling them usefully is very hard.
It sounds very ambitious; but then there are lots of smart people involved; I don't know.
The other alternatives are for LES results to be kept secret and used only for policymaking, or for the results to be public and incorrect. I suspect the former is most likely.
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.
Rather, it looks like a general research platform for social simulations. The various models could be broad or narrow in scope, well proven or highly speculative. Perhaps some models will also be built on the output of other models. With all the models and all the data in one place, hopefully it would start to become clear which are accurate.
The idea was that the client could tweak various features (numbers of judges, sentences for specific crimes, number of police on the beat) and look at unexpected secondary effects this would have, like increased time in probation or more prison overcrowding.
It was written in OCaml no less :-)
I wasn't involved in using the simulation that much, so I often wonder how accurate and effective it was in the end.
Seems they want to wire up every realtime data source they can get their hands on to a massive database, then allow researchers to upload apps to run on the data. So, there would be a variety of simulations running, using different models.
They would also provide access to the simulations at least to important decision makers. It's not clear exactly how open the access would be.
But it is always interesting when we catch up to classic sci-if and work towards actual implementations of what was pure imagination only a short time ago.
But I wonder how many simulations deep we are now???
Articles like this make me wonder if Eliezer Yudkowsky isn't so far off after all. If I ever meet him or Aubrey de Grey, I'll apologize for not taking them more seriously.
