In a recent essay, Brian Tomasik argues that meme-spreading has higher expected utility than x-risk reduction. His analysis assumes a classical utilitarian ethic, but it may be generalizable to other value systems. Here's the summary:
I personally do not support efforts to reduce extinction risk because I think space colonization would potentially give rise to astronomical amounts of suffering. However, even if I thought reducing extinction risk was a good idea, I would not work on it, because spreading your particular values has generally much higher leverage than being one more voice for safety measures against extinction in a world where reducing extinction risk is hard and almost everyone has some incentives to invest in the issue.
As you suggest with your "some" qualifier, my essay that benthamite shared doesn't make any assumptions about negative utilitarianism. I merely inserted parentheticals about my own views into it to avoid giving the impression that I'm personally a positive-leaning utilitarian.
