Culture War Roundup for the week of August 4, 2025

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

I follow JimDMiller ("James Miller" on Scott's blogs, occasionally /u/sargon66 back when we were on Reddit) on Twitter, and was amused to see how much pushback he got on the claim:

If I can predict what I doctor will say, I have the knowledge of that doctor. Prediction is understanding, that is the key to why LLMs are worth trillions.

On the one hand, it's not inconceivable that LLMs can get very good at producing text that "interpolates" within and "remixes" their data set without yet getting good at predicting text that "extrapolates" from it. Chain-of-thought is a good attempt to get around that problem, but so far that doesn't seem to be as superhuman at "everything" as simple Monte Carlo tree search was at "Go" and "Chess". Humans aren't exactly great at this either (the tradition when someone comes up with previously-unheard-of knowledge is to award them a patent and/or a PhD) but humans at least have got a track record of accomplishing it occasionally.

On the other hand, even humans don't have a great track record. A lot of science dissertations are basically "remixes" of existing investigative techniques applied to new experimental data. My dissertation's biggest contributions were of the form "prove a theorem analogous to existing technique X but for somewhat-different problem Y". It's not obvious to me how much technically-new knowledge really requires completely-conceptually-new "extrapolation" of ideas.

On the gripping hand, I'm steelmanning so hard in my first paragraph that it no longer really resembles the real clearly-stated AI-dismissive arguments. If we actually get to the point where the output of an LLM can predict or surpass any top human, I'm going to need to see some much clearer proofs that the Church-Turing thesis only constrains semiconductors, not fatty grey meat. Well, I'd like to see such proofs, anyway. If we get to that point then any proof attempts are likely either going to be comically silly (if we have Friendly AGI, it'll be shooting them down left and right) or tragically silly (if we have UnFriendly AGI, hopefully we won't keep debating whether submarines can really swim while they're launching torpedos).
