The issue, to me, is not whether they are distinguishable.
The issues are:
is there any relevant-to-my-values difference that would cause me to weight them differently? (answer: no)
and:
does this statement make any sense as pointing to an actual fact about the world: “‘I’ will experience being copy A (as opposed to B or C)” (answer: no)
Imagine the statement: in world 1, “I” will wake up as copy A. in world 2 “I” will wake up as copy B. How are world 1 and world 2 actually different?
Answer: they aren’t different. It’s just that in world 1, I drew a box around the future copy A and said that this is what will count as “me”, and in world 2, I drew a box around copy B and said that this is what will count as “me”. This is a distinction that exists only in the map, not in the territory.
