This sounds pretty obvious, but I would prefer to rephrase it as
follows:
Either there will be a posthuman phase or there won't. (If there won't,
the human race will die)
If there is a posthuman race, either they will conduct ancestor
simulation or they won't.
If they do conduct ancestor simulations, then we may be one of them.
This approach is restricted to a "time" point of view and obviously
ignores the fact that in the plenitude there is the certitude that all
these alternatives are satisfied. Hence there are ancestor simulations
and we are one of them! We are also the original! We are all copies that
satisfies consistent extensions (as Bruno says).
