I would like Bruce to consider the case Alice measures alternately x and z spin axes of an electron 1000 times and interprets those measurement results as binary digits following a decimal point to define the real number to which she will set her measurement angle to (before she measures her entangled particle). Certainly in the no-collapse case there would be at least 2^1000 Alices who perform the measurement at each of the possible measurement angles that can be defined by 1000 binary digits. What I wonder is how many Alices Bruce would believe to exist in this scenario before she measures her entangled particle.
