I guess this is one of the open questions that we agree to disagree
on. I don't believe cloning complicates the situation much (about as
much as twins do in our existing reality).

In any case, exact definitions would vary from individual to
individual, and from observer to observer. However, this does not stop
us from constructing a theory assuming a well defined class, and a set
of observers that agree about that class, without specifying the class
exactly. The properties ascribed to that class should therefore be
invarient of the exact definition.

Good grief! This is not even worth commenting on.

What about what your observers actually observe? That is random. This
appears to be a level of description problem again - from the bird's
eye view of the system, it evolves according to determinsitic laws -
this is what the ASSA is discussing. From the point of view of the
observer in the system (Max's frog perspective), the system is only
partially deterministic, with a large stochastic component. This is
the level of description that the RSSA operates on. Yes, this property
is related to the issue of emergence, and yes people seem to have
endless debates about emergence too, although I believe that issue is
largely resolved.

The two levels of description do not have the same predictions for the
same system, as the terminology employed in the two languages are
different. Just as the microscopic description of a gas cannot discuss
entropy. The microscopic decsription predicts reversible dynamics,
whereas the macroscopic description predicts the opposite. what must
be true is that a consistent connective theory must exist connecting
the two. In the case of thermodynamics and atomic theory, this is
given by statistical mechanics. In our case, the ASSA and the RSSA are
probably connected by a measurement theory of quantum mechanics,
something about which we have only the vague outline at present.
