Personally I think the third option is ‘obviously correct’. There isn’t really such a thing as a ‘thread of persisting subjective identity’. And this undermines the idea that in the quantum suicide scenario you should ‘expect to become’ the miraculous survivor.
All we can say is that the multiverse contains ‘miraculous observers’ with tiny ‘probability weights’ attached to them—and we can even concede that some of them get round to thinking “hang on—surely this means Many Worlds is true?” But whether their less unlikely counterparts live or die doesn’t affect this in any way.
Interesting post!
