Yes, but that is in no way inconsistent with what I said in the above, in
fact that's the reason that all versions of "you" agree on what the half
life of a radioactive element is, although they may disagree on whether a
particular atom has decayed or not.

Yes it's a very strange thing to say no doubt about it, but there is
absolutely positively no way any quantum interpretation that is compatible
with observation will EVER be able to make the quantum world not seem
strange. When you get down into the quantum realm things just seem weird,
but they never become logically paradoxical. The reason things seem so
strange to us is that there would've been no Evolutionarily advantage to
our hominid ancestors on the African savanna if our minds were constructed
in such a way that such things seemed intuitively obvious, so instead
evolution made our brains good at other things, like avoiding predators and
detecting prey.

Yes.

Yes. Is there supposed to be a problem with that?

And that would be a pity, but physicists would still have the ability to
multiply numbers and find their square roots, they were doing such
numerical manipulation long before anybody knew anything about Hilbert space
, so they could still use the Born rule. Regardless of what a mathematician
might say physicists will never abandon the Born rule as long as it retains
its ability to make successful predictions.
