At a more basic level, I think the situation is just actually much more confusing than human extinction in a bunch of ways.
(Separately, under my views misaligned AI takeover seems worse than human extinction due to (e.g.) biorisk. This is because primates or other closely related seem very likely to re-evolve into an intelligent civilization and I feel better about this civilization than AIs.)
