I take your claim in the post not to be “the fact that an offer is +EV is one strong reason to be in favor of it,” but rather “you ought to take the cosmic coin flip, risking the universe, just because it is +EV.” (Because being +EV definitionally means the good scenario is super unbelievably good, much better than most people considering the thought experiment are probably imagining.)
But even within the thought experiment, abstracting away all empirical uncertainties, I have enough philosophical uncertainty about EV maximization that I don’t want to take the bet.
The comment you replied to
acknowledges the value of x-risk reduction in general from a non-longtermist perspective
clarifies that it is making a point about the marginal altruistic value of x-risk vs AW or GHW work and points to a post making this argument in more detail
Your response merely reiterates that x-risk prevention has substantial altruistic (and non-altruistic) value. This isn’t responsive to the claim about whether, under non-longtermist assumptions, that value is greater on the margin than AW or GHW work.
So even though I actually agree with the claims in your comment, I downvoted it (along with this one complaining about the downvotes) for being off-topic and not embodying the type of discourse I think the EA Forum should strive for.
