I can understand the psychological appeal for self-unicity.
But I am not sure there is evidence for our analogicalness, nor
am I sure I understand the word.

I think, by some other mail you send, that you have understand
my proof that if we are digital machine there is no environment
at all, in the sense you are using here.
If you think that it is a sufficient reason to abandon the
mechanist hypothesis, why not. But nobody has ever gives a proof
of the existence of a 'substancial' neighborhood, so it is a
matter of religious belief or axiomatic hypothesis.

How can you check that 'anything' is thinking ? There is no possible
To *attribute* thinking is a kind of social betting strategy.
(Independently of the fact that 'God' knows the truth).
Turing test can help to make your mind, but it is neither
necessary (cf paralised people) nor sufficient (some people
HAVE attributed consciousness to Feigenbaum's ELIZA).

Remember that if we are digital machine, then, by the delocalisation
of consciousness, we are automatically facing the continuum, from a
first person perspective.
For exemple if our never-ending life depends on the value of any
decimal of Planck constant, we will ever make the experience of facing
the correct "Planck constant". This comes from the fact that the UD
dovetails on all computations on all real oracles (and the no-escape
branch have measure 0).
But I guess that is not what you mean. Is it?
So I am stuck in an abyss of perplexity when you define comp2 by
"a digital machine" can emulate (from a third person perspective) an
analogical machine.
I don't think James or any other many-worlder has ever say something
like that. It would be like to simulate 2$ with 1$.
Only dishonest people can do that, for a short time.
