So my counterargument is just that extinction is plausibly good in expectation on my views, so reducing extinction risk is not necessarily positive in expectation. Therefore it is not robustly positive, and I’d prefer something that is. I actually think world destruction would very likely to be good, with only concerns for aliens as a reason to avoid it, which seems extremely speculative, although I suppose this might also be a case of complex cluelessness, since the stakes are high with aliens, but dealing with aliens could also go badly.
I’m a moral antirealist, and I expect I would never endorse a non-asymmetric population ethics. The procreation asymmetry (at least implying good lives can never justify even a single bad life) is among my strongest intuitions, and I’d sooner give up pretty much all others to keep it and remain consistent. Negative utilitarianism specifically is my “fallback” view if I can’t include other moral intuitions I have in a consistent way (and I’m pretty close to NU now, anyway).
