Its many things. Interesting, strange, wonderful and so on but the
one thing it isn't is significant.
The continuation of an experiential history on some other earth, a
history common to the one that just ended here on this earth, is not
an effect on this earth. Its as insignificant to this earth as
things can be.
To this earth, perhaps, but it is significant on where you can be
next. The regions do not interact, but they still 1p statistically
interfere.
Eventually what you call this earth is a Moiré effect on infinitely
many computations under our substitution level, normally.

An infinite universe (Tegmark type 1) implies that our consciousness

That seems to imply that one's consciousness is unique and moves
around like a soul.
There's no dodgy metaphysical mechanism involved. If there are
multiple physical copies of you, and each copy has a similar
consciousness to you, then you can't know which copy is currently
generating your consciousness.
I think the idea is that the "stream of consciousness" is unified so
long as all the copies are being realized identically, in fact they
are not "multiple" per Leibniz's identity of indiscernibles. When
there is some quantum event amplified enough to make a difference in
the stream of consciousness then the stream divides and there are
two (or more) streams.
An implication of this is that if one of the streams terminates your
consciousness will continue in the other.
But it will, at best be *similar* to the deceased "you", just as I
am quite different from Brent Meeker of 50yrs ago. And there is no
quarantee that some stream will continue.
Similar is good enough. There is a guarantee that some branch will
continue if everything that can happen does happen.
Surely in an infinite universe, and assuming the identity of quantum
states, you don't need similarity - you will get a quantum state
that is a follow-on from your previous one, but in which you
continue to be alive...
Of course this depends on what it means for quantum states to follow
on from other ones. But our brains already seem to "know" what that
means, in that we feel we're the same person we were this morning,
and so we feel continuity of "similar enough" quantum states. Unless
QM is wrong about the nature of quantum states, we will feel
continuity if the "follow on" state is actually 10 ^ 10 ^ 100 light
years away (or 10 ^ 10 ^ 100 years away) from the preceeding state.
I agree but I don't think you need to refer to QM at all. The
conclusion would still follow in a classical infinite universe.
Probably not since classical physics is based on real numbers (and
so is quantum mechanics for that matter). Of course you could still
fall back on "similar enough". But in that case you will, as you are
dying, pass into a state of consciousness (i.e. none) that is
"similar enough" to a fetus (of some animal) or maybe a cabbage.
