I don't think we can answer that questions because we don't even know what "I" is. Are we even "the same person" from one minute to the next? Are we a different person with the same memories? My wife had a rare condition called Global Transient Amnesia three times and I was there for all three occurrences. In essence she temporarily forgets the last few years and cannot form new memories. One remarkable thing that happens is that she will be caught in a loop that last 20-40 seconds. She'll reset and repeat the exact same dialog. This to me intuitively drove the point home that we in a way are just passengers on a somewhat deterministic machine. At that point it practically becomes a somewhat religious assertion though.

for sure we're on a deterministic machine. i didnt presume consciousness being ineffable implies free will.

Derek Parfit had a lot of good writing on this subject.

I don't see the paradox. "I" is a notion of semantics.. all there is is interacting wavefunctions behaving according to physical laws. There is nothing else.

This seems entirely self-consistent and non-paradoxical.

it is but none of it includes the subjective experience part, which is the part I find paradoxical. subjective experience itself makes no sense. Where would I go "experientially" as my "self" is split? to the left or the right? I know the answer is, "nowhere, there is no 'I'". but to imagine it experientially, seems as though I'd find myself on one side or the other.
