No. Searle's arguments against strong AI have nothing whatsoever to do with the substances out of which we make computers. I can distill Searle's arguments against strong AI down to two sentences: 1) syntax does not give semantics, so formal programs don't cause minds. and 2) computations exist only relative to an observer, and "computation" does not name a physical process anyway, so it makes no sense to consider the brain a digital computer. -gts ========================================== Need Something?
