Existential risk might be worth talking about because of normative uncertainty. Not all EAs are necessarily hedonists, and perhaps the ones who are shouldn’t be, for reasons to be discovered later. So, if we don’t know what “value” is, or, as a movement, EA doesn’t “know” what “value” is, a priori, we might want to keep our options open, and if everyone is dead, then we can’t figure out what “value” really is or ought to be.
