Hi Hal,
I agree with everything you wrote about duplication...but I have to
take issue with your last point.

I think that the survival would be meaningful for the civilisation
doing the broadcasting so long as at least one daughter universe is able
to replicate the civilisation, just as I have meaningfully survived so
long as future versions of me exist somewhere in the multiverse, even if
I only survive in an infinitessimally small fraction of the universes
(Quantum Immortality).
