To Jesse: You apparently completely separate the probability of x and
x' from the similarity of x and x'.
I am not sure that makes sense for me.
In particular how could x and x' be similar, if x', but not x, involves
a 'white rabbit events'.

To Hal: I don't understand how an OM could write a letter. Writing a
letter, it seems to me, involves many OMs. Evolution, and more
generally "computational history" *is* what gives sense to any of the
OM. What evolves is more "real" that the many (subjective or objective)
bricks on which evolution proceeds and histories locally rely.

To Russell: I don't understand what you mean by a "conscious
description". Even the expression "conscious" machine can be misleading
at some point in the reasoning. It is really some person, which can be
(with comp) associate relatively to a machine/machine-history, who can
be conscious.
Imo, only a person can be conscious. Even the notion of OM, as it is
used in most of the recent posts, seems to me be a construction of the
mind of some person. It is personhood which makes possible to attribute
some sense to our many living 1-person OMs.
