Nor do I see a paradox, unless one tries to assert
that Person-A and Person-B are really the same person
or that they share the same identity. Person-A and
Person-B are related only in so much as they, as you
say, "share a common root."
However the point of my message here was not to
address that paradox, but rather to address the means
by which the original "root" person will experience
himself to walk into the entrance of the bifurcation
chamber and leave by one exit and not the other. This
is I believe essentially the same question that arises
when one considers the bifurcation of the observer in
MWI.
The root Person will experience a continuation of self
as he enters and leaves the bifurcation chamber. He
will emerge from the chamber from one of the two
exits, with equal probability of emerging from either
of them. If while exiting he looks to his right (or to
his left, depending on his exit door) he will see
someone virtually identical to him leaving by the
other door. He and his near-duplicate will then go on
to experience different experiences and develop
different personalities, such that they and third
parties will eventually come to recognize them as
different people. (In fact they are different
personalities at the moment of the bifurcation, though
these differences would be too small to be immediately
apparent.)
The main point of my message, however, is that the
relationship between the two bifurcations will be
identical to that of bifurcated observers in two
alternate universes in a MWI multiverse, except in so
much as they will be living and evolving in the same
universe. This gives us a new way to think about the
problem.
