Culture War Roundup for the week of February 23, 2026

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.

Ok. Here is one from me. GPT-52 wrote it to spec. The idea was human generated. You can use freecad, build123 or cadquery. Or if some of the bigguys have internal script - also their software.

Task: Parametric 3D-Printable Enclosure for ESP32 DevKit + Expansion Board

Design a fully parametric, 3D-printable enclosure (base + hinged lid) using scripted CAD. The enclosure houses: an ESP32-WROOM DevKit (30-pin) plugged vertically into a 30-pin ESP32 expansion board

  1. Expansion board (primary PCB) Size: 65 × 55 × 1.6 mm Mounting holes:4× Ø3.2 mm pattern 60 × 50 mm hole centers 2.5 mm from PCB edges PCB origin: lower-left corner, Z=0 at PCB bottom

  2. DevKit board (secondary PCB) Size: 55 × 28 × 1.6 mm Plugged into expansion board via headers Vertical offset: 11 mm above expansion PCB Max component height above DevKit PCB: 10 mm

  3. Enclosure requirements Wall thickness: 2.0 mm Base thickness: 2.4 mm Internal PCB edge clearance: 1.0 mm Internal corner fillets: ≥ 1.0 mm No supports; base printed flat

  4. Standoffs 4 standoffs under expansion board mounting holes Height: 6 mm Boss OD: 8 mm Fastening: M3 through-hole + hex nut trap (nut: 5.5 mm AF, 2.4 mm thick)

  5. Openings / features USB opening for DevKit USB connector Power opening (generic Ø8 mm) on side wall Ethernet opening 16 × 14 mm on side wall 2 LED holes Ø3 mm aligned to DevKit LED Assume connector centerlines are aligned to PCB mid-height unless otherwise stated

  6. Lid and living hinge Lid attached on one long edge Printable living hinge for PETG hinge thickness: 0.4 mm hinge width: 16 mm include stress-relief geometry Lid must clear tallest component by ≥2 mm Lid includes a snap latch on the opposite edge

  7. Parametric requirements Expose at least: PCB size Mount hole pattern Stack height Wall thickness Clearance Hinge thickness

We'll take it into consideration, thanks.

I think that CAD/CAM system are very good showcase - first - they are somewhat programming language - you can create any shape by steps. The models are not trained on that specifically - and you can have quite a bit of benchmark proofing.

For the record my local codex 5.3 created quite ok-ish representation of the task in 5-6 minutes. So probably something more complicated.

We don't really want a "showcase" in the sense "look at X impressive thing that Y model can do". There are a gazillion demos out there.

We want specific tasks that someone doubts a model can do, but which they'd be impressed by if they succeeded and which the two of us a priori think will work. If it would be super impressive (if it worked) but we don't think it would work, it's not what we want right now.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
