Yes, but does this problem need to be solved? I have no problem with
the idea that some "physical object" (in one computation) can be
"interpreted" in all sorts of ways - depending on how you map it. Does
it matter if there exists a (weird) mapping between a rock and a
universe with conscious inhabitants? The universe doesn't depend on the
rock for its existence so who cares!
