I'm ok with that... as I said to Stathis, those program have infinitesimal measure... that what I call HP world. What is important in computational hypothesis is computation, HP are corner case of computation... they are (a tiny) part of the infinity of instantiation below our level of substitution. > It might be true, but I don't think it follows from comp=digital brain > substitution and I think it introduces other problems. > It doesn't...
