Culture War Roundup for the week of October 6, 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.

China just chose the nuclear option:

TLDR:

China’s Ministry of Commerce just created an extra-territorial export-control net around rare earths and anything made with Chinese rare-earth technology. The bar is set extremely low, so this will ripple through EVs, wind, electronics, and defense supply chains worldwide.

(Assuming that this isn't a ploy designed to be a bargaining chip in order to get Trump to overturn export restrictions on advanced chips).

Now, while rare earths are very much not rare (though they do come from the earth, mostly), 90% of the actual processing happens in China, even if many deposits are elsewhere. Why is that the case? Well, rare-earth mining is not the most eco-friendly of industrial processes, and everyone else prefers it happen outside their backyards.

Just about every consumer and commercial electronic item is wrapped up in this. China dominates processing and magnet making, so the 0.1% trigger will catch a very large share of motors, drives, sensors, HDDs, speakers, drones, missiles, EVs, and wind-turbine components that contain NdFeB or SmCo magnets.

Assuming that a pleasant agreement isn't reached by Trump and Xi, this is going to do numbers on the trout population, and the economy. I don't even have to specify which economy, it's that global. It'll take years to onshore or friend-shore processing, even if deposits could ramp up to meet the demand. Really, I can't stress the chaos this will cause if the Chinese truly exercise their discretion, so we're going to have to strap in and see. Maybe nothing ever happens, maybe it does.

Obviously the best solution for the US is to bring all of these capabilities in-house (to one degree or another) but the funniest solution would just be to say "these Chinese have made their ruling, let them enforce it" and then buy secondhand from India, same way the Russians have been getting around our sanctions.

Obviously the best solution for the US is to bring all of these capabilities in-house

Actually, the best solution would be for the US to perform a magic ritual, invoking Moloch and begging him to supply them with rare earth metals in exchange for sacrificed children - which is more likely to succeed than your proposal. The USA isn't actually capable of replacing China's role in the productive economy in any timeframe that's actually relevant. Do you think the tech and defence industries can sustain a complete pause in production for the 10-15 years it'll take to onshore this stuff? This means no more harddrives, no more lithium batteries etc.

It's not an either/or, the US can pursue onshoring as a permanent long-term solution while pursuing other avenues in the interim.

The USA isn't actually capable of replacing China's role in the productive economy in any timeframe that's actually relevant.

Replacing China's worldwide economic production isn't necessary; what the US ideally needs to be able to do is fulfill domestic national security needs. Nevertheless, it's worth noting that the US (re)opened a single rare earth mine in 2018 and in a couple of years it supplied 15% of worldwide production.

This means no more harddrives, no more lithium batteries etc.

First off, it does not. It means the Chinese are putting regulations on export. If you read the article it suggest the Chinese will likely ban exports to defense companies. So yes, I suspect the tech and defense industries will actually be able to source harddrives, lithium batteries, etc. for the next 5 - 10 years.

Why? Well, setting aside the fact that the US actually has at least some rare earth mining and refining capability in-country (and is currently, as I understand it, in the process of building more, so 7 - 10 years to have at least some replacement for Chinese goods is probably pessimistic even if you don't assume the US invokes national security to cut through red tape), I'd just remind you that Russia has been able to source actually embargoed items for its military from Western sources despite the US having a much better ability to deploy soft and hard power worldwide to sanction them than China does to sanction the US. If the Chinese move to cut US defense firms out of the loop, that

  1. Does not impact the tech sector, and
  2. Is no guarantee that the US won't just import them via shell companies.

There is almost no big USA company that has not some DoD contracts.
