Colin: The Wright Bros did not simulate _*anything*_.
They*REPLICATED* the physics. (Computers didn’t exist then!) That’s the whole point of my CERN remark.**** Here is the Wikipedia definition of Simulation: *Simulation* is the imitation of the operation of a real-world process or system over time.[1]<http://en.wikipedia.org/wiki/Simulation#cite_note-definition-0>The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time. Obviously, a wind tunnel is used to simulate the characteristics that one might expect to find with a larger model, or a model that is to fly higher and in natural conditions. Now you have made a good point that a computer simulation of how the brain works is not the same as having a simulation using the same kind of material that brains work with. By this standard, then, the simulations that neural scientists HAVE made using collections of neurons would constitute a TRUE simulation or what you have called "replication" (if indeed the wind tunnel is a "replication"of the conditions that one is wishing the model to represent.) I would say, drop the special meanings of the terms and the bad metaphors and the morphed facts and just stick to the point. (Sheesh, no wonder it is so difficult for you.) There is enough evidence to suggest that the computer has a number of characteristics to allow it to simulate the working of a mind to such an extent that, at the very least, it would be analogous to the testing of an airplane by using a model in a wing tunnel (along with using a number of other simulation tests). It is difficult (and a little absurd to even try) to quantify that evidence. However, that does not mean that the evidence does not exist. --It’s a little harder to see what’s happening in a brain, but the principle is sound. It's also a little harder to see what's happening in the future but the principle of an expectation of incremental advances is sound.
