The distinction between humans and other lifeforms is arbitrary.
~10^30 lifeforms have ever lived.
Thus, there’ll likely be another ~10^30 lifeforms.
But it’s equally likely that this will be:
~10^30 non-human animals, if we do go extinct (life originated ~5bn years ago and life will end in ~5bn years when the sun dies).
~10^30 (post-) humans, if we don’t go extinct (as per Bostrom’s calculation).
And so the doomsday argument doesn’t tell us anything about x-risk or the far future.
