It seems to me that we automatically get a 'fixed identity' when we consider each
observer's 1p to be defined by a bundle or sheaf of an infinite number of computations.
The chooser of A and of B is one and the same if and only if the computational bundle
that make the choice of A also make the choice of B. What you are considering is just an
example of my definition of reality.
But what makes the bundle or sheaf stay together? As computations why don't they quickly
diverge? That's the question I was raising in the Moscow/Washington thought experiment.
We know the M-man and the W-man diverge because they experience different things. But
they experience different things because their physical eyes/skin/ears... are in
differenct physical places? And those experiences form two different sheafs of
computation that have a lot in common within each and differences between them. But there
is no computational explanation of why that should be so. Computationally there could be
just one sheaf including the M-man and the W-man just as the drone pilot has a sheaf that
includes Florida and Afghanistan. So the argument for comp seems to rely on physics.
