Thanks for highlighting this Michael and spelling out the different possibilities. In particular, it seems like if aliens are present and would expand into the same space we would have expanded into had we not gone extinct, then for the totalist, to the extent that aliens have similar values to us, the value of x-risk mitigation is reduced. If we are replaceable by aliens, then it seems like not much is lost if we do go extinct, since the aliens would still produce the large valuable future that we would have otherwise produced.
I have to admit though, it is personally uncomfortable for my valuation of x-risk mitigation efforts and cause prioritisation to depend partially on something as abstract and unknowable as the existence of aliens.
