See my answer to Brent. Once A1 looks at itself in the mirror (and
thus A2 too, given the protocol). A1 sees MA1 and A2 sees MA2, and the
computation differs. It is like being duplicated in two identical
rooms. This change the (local and relative) measure, because if you
open the "box" in the room you will find zero or one, but not both.

Not if you distinguish first person and third person. It is the third
person computations which gives the local relative probabilities, but
yes the stream of consciousness (first person) is the same. This lead
to a vocabulary problem like chosing the word "bifurcation" or
"differentiation" for computation which, at some point *becomes*
different.
Consciousness is unique and immaterial. As such it resides in
"Platonia". Life, that is embedding in relative computaional histories
is what makes consciousness differentiate.

You are right, but different computations can be understood locally
and globally. The "computation of me up to Washington is different of
the computation of me up to Moscow, even when I am still in Brussels.
It is contained in the Y = II idea. Note that the same "vocabulary"
problem occurs with Quantum Physics.
Of course we still lack a definite criteria of identity for
computation. But we can already derive what can count as different
computations if we want those measure question making sense.
