That is a good argument, at least under Boltzmann's view.  But that may be wrong.

Oh, that's the old 1994 Greg Egan scenario in Permutation City.  Of course.

Of course, at least to outward observers.  You would report what ever you report.
It does not *necessarily* follow that you experience anything. Recall the horrible
GLUT (Giant Lookup Table) which performs no computations but reports vived

I concede that it is *possible* that I would have experiencs under reversed
computations;  I dispute that it can be proven.
