I believe that it is because, on the one hand, we don't accept fuzzy results, and on the other hand, we don't know how to train the millions of ANNs required to mimic a mammal's brain. The way in which biology deals with failures, faults and defects is far beyond our full comprehension. How to program a brain? and similar questions are beyond our grasp too, yet, we re-program ourselves day after day intuitively.
In some way, the speed at which multicores are evolving (more and simpler cores instead of a single, yet powerful one) indicates that parallel processing is the way to go -I think I read it somewhere in this list-. Maybe the answer that the evolution found for carbon-based processing is different than the one for future silicon-based life forms (or at least, intelligent processing). A dead company used to say "the computer is the network", and for our brains it seems so. Will it be true for really-massive processors? Will they shrink until they only sum and bias inputs without any programing inside? Will we discuss multi-million-core-SMP? If so, I doubt that it will be single-bus-based solution. I'm not sure I'll live until we find an answer, but is a nice long term research topic.... ariel El 16/02/11 12:29, "C.
