Don't you think a good definition of causality (i.e. whether event A causally influenced event B) should be observer-independent? Anyway, chrisfosterelli alrea

Don't you think a good definition of causality (i.e. whether event A causally influenced event B) should be observer-independent? Anyway, chrisfosterelli already elaborated on why thinking of the collapse at A "causing" the collapse at B is not a good idea from the perspective of quantum mechanics, either.
