You may well be right, my point only was that the intuition pump fails at the realistic levels of complexity of the recordings involved. I think Bruce appreciates this at least. > As for the looking-table, it need to be infinite if it > implements a universal machine. Not for implementing a finite subsequence of a computation as discussed in the MGA. Let us say we're interested in a 10 second sequence of observer moments. Running a program emulating that sequence might involve the machine passing through some 10^15 32 bit states (say - I'm just plucking figures from where the sun don't shine here). Then to add in the counterfactual nature of this, we would just need to create a lookup table with 32 ^ (10 ^ 15) entries in it. Rather large, agreed, but last time I looked, a lot less than infinite. -- ---------------------------------------------------------------------------- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics hpco...@hpcoders.com.au University of New South Wales http://www.hpcoders.com.au Latest project: The Amoeba's Secret (http://www.hpcoders.com.au/AmoebasSecret.html) ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
