usually many relates it two consciousness and assumes that when the

to get the reversal.
Maybe that is the basis of the problem. In step 3 you seem to be
claiming nothing that could not be achieved by a non-conscious
machine:
Yes.
take a machine that can take photographs and compare the resulting
images with a data base of images of certain cities. When a match is
found, the machine outputs the corresponding name of the city from
the data base. Send one such machine to Washington and an identical
machine to Moscow. They will fulfill your requirements, the W-
machine will output W and the M-machine will output M.
This is what you are now seeming to describe. But that is not FPI.
How could the machine predict the result of the match? Give me the
algorithm used by that machine.
The "P" in the acronym stands for "person", and if the "person" is
not conscious, it is a zombie and any output you get has no bearing
on what will happen to conscious persons.
The problem is a problem of prediction of future first person account.
The zombie machines will probably not be aware of each other, but
from that you cannot conclude that the conscious persons will not be
aware of each other, or that consciousness necessarily
differentiates on different inputs.
Well, you need the inputs being enough different (like seeing W, resp.
M) so that the machine can take notice of the difference, and write
distinct outcome in the diary, of course.
