(Epistemic status: mostly observation through heavy fog of war, partly speculation)

From your previous comment:

The "educated savvy left-leaning online person" consensus (as far as I can gather) is something like: "AI art is bad, the real danger is capitalism, and the extinction danger is some kind of fake regulatory-capture hype techbro thing which (if we even bother to look at the LW/EA spaces at all) is adjacent to racists and cryptobros".

So clearly you're aware of / agree with this being a substantial chunk of what's happening in the “mass social media” space, in which case…

Given this, plus anchoring bias, you should expect and be very paranoid about the "first thing people hear = sets the conversation" thing.

… why is this not just “お前はもう死んでいる” (that is, you are already cut off from this strategy due to things that happened before you could react) right out of the gate, at least for that (vocal, seemingly influential) subpopulation?

What I observe in many of my less-technical circles (which roughly match the above description) is that as soon as the first word exits your virtual mouth that implies that there's any substance to any underlying technology itself, good or bad or worth giving any thought to at all (and that's what gets you on the metatextual level, the frame-clinging plus some other stuff I want to gesture at but am not sure whether that's safe to do right now), beyond “mass stealing to create a class divide”, you instantly lose. At best everything you say gets interpreted as “so the flood of theft and soulless shit is going to get even worse” (and they do seem to be effectively running on a souls-based model of anticipation even if their overt dialogue isn't theistic, which is part of what creates a big inferential divide to start with). But you don't seem to be suggesting leaning into that spin, so I can't square what you're suggesting with what seem to be shared observations. Also, the less loud and angry people are still strongly focused on “AI being given responsibility it's not ready for”, so as soon as you hint at exceeding human intelligence, you lose (and you don't then get the chance to say “no no, I mean in the future”, you lose before any further words are processed).

Now, I do separately observe a subset of more normie-feeling/working-class people who don't loudly profess the above lines and are willing to e.g. openly use some generative-model art here and there in a way that suggests they don't have the same loud emotions about the current AI-technology explosion. I'm not as sure what main challenges we would run into with that crowd, and maybe that's whom you mean to target. I still think getting taken seriously would be tricky, but they might laugh at you more mirthfully instead of more derisively, and low-key repetition might have an effect. I do kind of worry that even if you start succeeding there, then the x-risk argument can get conflated with the easier-to-spread “art theft”, “laundering bias”, etc. models (either accidentally, or deliberately by adversaries) and then this second crowd maybe gets partly converted to that, partly starts rejecting you for looking too similar to that, and partly gets driven underground by other people protesting their benefiting from the current-day mundane-utility aspect.

I also observe a subset of business-oriented people who want the mundane utility a lot but often especially want to be on the hype train for capital-access or marketing reasons, or at least want to keep their friends and business associates who want that. I think they're kind of constrained in what they can openly say or do and might be receptive to strategic thinking about x-risk but ultimately dead ends for acting on it—but maybe that last part can be changed with strategic shadow consensus building, which is less like mass communication and where you might have more leeway and initial trust to work with. Obviously, if someone is already doing that, we don't necessarily see it posted on LW. There's probably some useful inferences to be drawn from events like the OpenAI board shakeup here, but I don't know what they are right now.

FWIW, I have an underlying intuition here that's something like “if you're going to go Dark Arts, then go big or go home”, but I don't really know how to operationalize that in detail and am generally confused and sad. In general, I think people who have things like “logical connectives are relevant to the content of the text” threaded through enough of their mindset tend to fall into a trap analogous to the “Average Familiarity” xkcd or to Hofstadter's Law when they try truly-mass communication unless they're willing to wrench things around in what are often very painful ways to them, and (per the analogies) that this happens even when they're specifically trying to correct for it.
