Non X-risks from AI are still intrinsically important AI safety issues
Sure but I think they are less intrinically important for the standard ITN reasons.
I think that your statement implies that we should care about them a similar amount to longtermist motivated safety which might be true but you don't make a case for why we should care. I don't think the reasons for prioritising LT AIS are strongly correlated with the reasons for prioritising NT AIS so it would be somewhat surprising if this were true.
If the people you ultimately want to influence are the technophiles who are building AI, who regard most near-term 'AI safety' people as annoying scolds and culture warriors, it could be good to clearly differentiate yourself from them. If existential safety people get a reputation as reliable collaborators, employees and allies who don't support the bad behaviour of many AI bias people this could put us in a good position.
I think I disagree with the general direction of this comment but it’s hard to state why, so I’ll just outline an alternative view:
Yes, I agree with this. I think in general there is a fair bit of social pressure to give credence to intellectually weak concerns about 'AI bias' etc., which is part of what technophiles dislike, even if they can't say so publicly. Pace your first sentence, I think that self-censorship is helpful for building reputation in some fields. As such, I expect honestly reporting an epistemically rigourous evaluation of these arguments will often suffice to cause 'isolation and mutual dismissal' from Gebru-types, even while it is positive for your reputation among 'builder' capabilities researchers.
Note that in general existential safety people have put a fair bit of effort into trying to cultivate good relations with near-term AI safety people. The lowest hanging fruit implied by the argument above is to simply pull back on these activities.
