Both M and W man would have a continuous feeling of identity with H man. I don't see
that you two really have opposing viewpoints, although as usual I may be missing something.
Of course if the brain can't be considered digital at any level (as Kermit suggests)
then this is actually impossible, and the question doesn't arise. But personally I'm not
about to embrance the idea that the universe is analogue all the way down - with the
problems that causes (like the "ultraviolety catastrophe") - and if it's digital at any
level, this will work.
Even if it's digital it can't be cloned at the quantum level. So the process couldn't be
implemented if copying all the way down to the quantum state were necessary. But I don't
think this is the case. Tegmark, among others, has shown that the brain is too hot to
maintain quantum superpositions - so we can probably assume that classical copying is
enough, with at worst a little loss of short term memory. It's interesting to consider
though how accurate the copying would have to be for Bruno's question to make sense.
Suppose the M and W man only retained a random 10% of the H man's memories?
