When you say the time of your birth is not special, you are already trying to judge it objectively. For you personally, the moment of your birth is special. And more relevantly to the DA, from a first-person perspective, the moment “now” is special.
From an objective viewpoint, discussing a specific observer or a specific moment requires some explanation, something process pointing to it. e.g. a sampling process. Otherwise, it fails to be objective by inherently focusing on someone/sometime.
From a first-person perspective, discussions based on “I” and “now” doesn’t require such an explanation. It’s inherently understandable. The future is just moments after “now”. Its prediction ought to be based on my knowledge of the present and past.
What the doomsday argument saying is, the fact “I am this person” (living now) shall be treated the same way as if someone from the objective viewpoint in 1, performs a random sampling and finds me (now). The two cases are supposed to be logically equivalent. So the two viewpoints can say the same thing. I’m saying let’s not make that assumption. And in this case, the objective viewpoint cannot say the same thing as the first-person perspective. So we can’t switch perspectives here.
