If many different universes exist, and one of them has infinite number of all possible observers, SIA imply that I must be in it.
But if infinite number of all possible observers exist, the condition that I may not be born is not working in this universe and I can’t apply SIA to the Earth’s fate. Doomsday argument is on.
