I am not getting into this. We already did this discussion two years ago. Besides, Turing identity is totally irrelevant to the issue of whether a given Turing process should be considered a singleton or a community, and you know it.
No offense. But if there's any AI-literate being on the planet who doesn't have strong, unarguable opinions on Strong AI, I would like to meet him.
As for myself, of course, I have always held that the laws of physics are non-Turing-computable and there is no observer-independent answer to the general form of the question "Does process A instantiate computation B"? Likewise, you are a strong computationalist: Everything is Turing-computable and the phrase "non-Turing-computable" is synonymous with ghosties and ghoulies. The chance that either of us will change opinions without totally new arguments equals the probability that we will both become fanatic Calvinists.
