Hi Bruno,

thanks for your interesting answer, I have some questions though.

I would equate total amnesia with death (we've been through this before,
Stathis has written about this, if I remember correctly).

I agree with you that you can't have a universal machine stopping
relatively to all others from it's POV; but I don't see why we can't
think of it having total amnesia. So, for the time being, let us take
surviving as meaning to keep (at least large parts) of one's memory.

Could you elaborate? I don't see why LG should be bad news for comp?
You mean because LG proposes a fundamental spacetime quantization?
I don't see how it would falsify comp?

And why the finitely describable Big Bang? It seems you have a problem
when there are some finite limits (outside of the effective computation
of mind). Is this because you need the continuum in the AUDA to get
Quantum logic or something like that?

Why do you believe that latter?

What continuations are possible in arithmetic? I would like to warn
against the approach of taking conceivability/ "humand mind" logical
possibility as a criterion (as you seem to suggest with saying that "the
transporter failed" is a consistent extension). The criterion for
continuation must be arithmetic possibility, and here, I don't see any
formal or even informal way to get to "worlds" in the anthropocentric sense.

Will do :-) But I think beforehand we should clear up any mutual
misunderstandings; you have obviously been thinking about these things
for a long time, and you have made connections/inferences which may not
be as obvious as you think.

BTW: thanks for your modal logic post (the Dt explanation), here again
the above mentioned issue crops up: while the modal logic may be
elemental, your interpretation of them is certainly not.

Often it is the interpretation that does all the work (consider for
instance Einstein's SR: the mathematics was there before, he "just"
suggested a new interpretation by adding postulates (Principle of
Relativity for electrodynamics, c as constant speed of light)).

These interpretation issues are often played down, but they are in fact
essential.

Cheers,
Günther
