I think the legal aspect matters. And once someone downloads an ATproto post it’s not going to vanish by the author deleting it either. There is a freely available archive tool that lets you download your entire Bluesky post history with two clicks. And given how ATproto works, that means you can use the same tool to download, archive and search another users entire history of posts as well

reminder, the Bluesky team explicitly mentioned commercial use of their data in their 2024 arXiv preprint:

“…as Bluesky grows, there are likely to be multiple professionally-run indexers for various purposes. For example, a company that performs sentiment analysis on social media activity about brands could easily create a whole-network index that provides insights to their clients. Web search engines can incorporate Bluesky activity into their indexes,…” pg. 5

Is that what is happening here? I think these arguments stem from deep concern; unfortunately that isn’t enough to make them compelling. I genuinely wish it were as simple as “this seems bad, let’s not do this”, but unfortunately I think it really is not. As @SyliviaFysica said, the very fact that developments are so concerning makes it all the more important that we don’t fool ourselves. In that context, I don’t feel it’s the ethical issues that I’m struggling with, it’s that the introduction of LLMs seems both so transformational and so uncontrollable.

2026-03-11T08:50:24Z

‘Technology is not inevitable. We can just not do LLMs.
Tobacco apparently is an illustrative example. Asbestos too.’

Cigarettes are still on sale. Tobacco companies still exist. Despite decades of monumental efforts. And the parties deeply invested in developing AI technology are not just large corporations but the most powerful state actors on the planet.

Asbestos is a distinct physical substance, that we can detect and remove. LLMs produce linguistic output which is not. Text is infinitely replicable and can seamlessly be transformed into another modality, speech. The linguistic output of LLMs is impossible to reliably distinguish from human output by its very nature.

I’m also inclined to think that online social media has played a big part in this and that it was a consequential step into a negative feedback loop when the news started reporting on “what people are talking about on Twitter right now” - not only is virality on social media not epistemologically grounded in the right way, the growth of social media undermined the advertising model of legacy media, leading to shrinking resources for direct reporting, and ever greater journalistic reliance on what is being said, which in turn….

Relatedly, the most productive way to deal with baseless comments is to try and see what about the manuscript might have led them to go wrong….

not always, but quite often, there are fairly simple fixes that cut off entire paths to error. These can, in fact, make papers better, last but not least, because scientific papers are attempts to *communicate to a specific audience*

it is conceptually odd to have the evaluation of communicative success happen by anyone other than that target audience, and it feels like it would require lots of empirical work to show replacing a sample of the intended audience with some “other” (human or machine) didn’t lead to outputs that were ultimately less fit for purpose

my question is more “what’s the feasible alternative” - at the core of the AI problem is the ability for (sheer endless) over-production relative to our capacity to process, evaluate, and integrate results. That structural problem doesn’t magically evaporate because you get rid of commercial publishers, or a particular unit of scientific record keeping and dissemination

given that science is a communal, inter-subjective, incremental endeavour it’s going to need *some kind of* records for information. And if the problem is “too much information”, how will the format alone solve it?

In reply to nevent1q…u2xh
_________________________

that is a helpful distinction and related to what I'm interested in here, but more in an implicit way, and I'm interested in capturing that implicit bit more clearly.
To put it differently, I could potentially be an expert on a topic but, say, publicly act as a lobbyist, so 'expertise' is relevant here by virtue of (genuine) expertise requiring a mode of engagement that engages with all of the evidence.

So expertise requires the particular mode of engagement that I think characterises science, but the fact that I'm an expert doesn't necessarily make all my communications in that mode.

And if what I'm trying to understand are lines like that between 'objective/subjective' or 'political/apolitical' I think that mode matters.

random thought: discussions around the relationship between science and politics, science and values, or science and activism have never completely resolved into a satisfactory answer for me and I just wondered whether the real issue is that science and political action are associated with *different modes of engagement*.

Scientific integrity, to me, includes engaging in good faith with all of the evidence, that means also a demand to engage with arguments by 'the other side'. Politics or activism does not require me to do that in any shape or form (though some such engagement might sometimes be instrumentally useful). That's the actual tension...

all of the discourse between 'objective' and 'subjective' or 'apolitical politics versus everything is political' is stuck on not quite the right thing

I take “productivity” to refer to the efficiency of production of a good or service

readily available AI systems now can (and do) produce essay answers that I would have to assign a passing grade (and actually an increasingly good grade) given our marking criteria, and it can do that in seconds. It’s a huge problem for higher education.

How is that not a “productivity gain”?

I find the conflation of questions about what these systems can actually do (an empirical question!) with questions of desirability deeply counter-productive.

there are massive “productivity gains” everywhere:

- higher education is demonstrably being undermined by the fact that course work can now be (and is being) completed by AI query
- science is demonstrably buckling under a deluge of submissions
- democracy is demonstrably being harmed by AI based astroturfing

all of these are well-documented. “Controlled experiments” are not the only form of evidence ….

I’m saying that any kind of NN whose target task is predicting what happens next (for example, next token prediction in the context of LLM training, or a recurrent network a la Elman, or the Bayesian brain hypothesis) elides the difference between an “external guide” and self-driven adjustment.

the whole point about those tasks, conceptually, is that they provide teaching without a teacher….

interesting thoughts, Nate! Personally, I find the points about the complexity of neurons more relevant in this context than the contrast to “being tuned by some external actor” given that a prediction task like next token prediction etc. feels like it elides that difference between the internal and the external…

interesting! I guess for me personally it really depends on what one’s specific question is: for me, those questions have always been about understanding *behaviour*. It’s then not a big step to take a connectionist model and say something like “well this particular error minimisation technique isn’t biologically plausible, but the main explanatory work is being done by the fact of some kind of error minimisation process over this kind of architecture…” so you can kind of conceptually bracket that (as a kind of note to self: one day fill in more biologically plausible component)… whereas if your primary explanatory target is the brain itself then that same mismatch is a much more fundamental problem

This is an amazing book. I came across it only because Erin Kissane (npub1sac…kcpe) mentioned it in passing a while back and it took me some time to get through, but I think it’s among the most clarifying books I’ve ever read. Anyone with even a passing interest in online communication should read it:
