OK. It's going to be coming out soon because of the relentless investigations of Pam Bondi and Kash Patel, so I might as well admit it before the news breaks:

You're right. According to Wikipedia, there are only two topologically distinct 8-vertex hexahedra: the cuboid, and the doubly truncated tetrahedron. My argument should work for both cases, provided that we choose a vertex that is not on a triangular face.

I will assume that the polyhedron is convex. By Euler's theorem it has 12 edges, and so every vertex has degree 3. Choose a vertex P, and let A, B, and C be the vertices adjacent to P. Then ABC is a triangular cross-section. If the plane is moved epsilon away from P the cross-section is hexagonal.

I’ve been full targeted by fascist trolls twice. 1st, local PD started doing drive-bys, cuz *they* were freaked out by the threats. 2nd, Jesus the 2nd, as I sat by my dad’s deathbed fascists posted my kids’ name & school & described in detail how they planned to murder them. Fucking “party of life.”

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n

Abstract: Under the banner of progress, products have been uncritically adopted or
even imposed on users — in past centuries with tobacco and combustion engines, and in
the 21st with social media. For these collective blunders, we now regret our involvement or
apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we
are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not
considered a valid position to reject AI technologies in our teaching and research. This
is why in June 2025, we co-authored an Open Letter calling on our employers to reverse
and rethink their stance on uncritically adopting AI technologies. In this position piece,
we expound on why universities must take their role seriously toa) counter the technology
industry’s marketing, hype, and harm; and to b) safeguard higher education, critical
thinking, expertise, academic freedom, and scientific integrity. We include pointers to
relevant work to further inform our colleagues.

Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI
(black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are
in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are
both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and
Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf.
Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al.
2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA).

Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms
are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

Excuse me? “Freedom of speech”?
The media lies about Kirk’s life have already started.

The guy founded the premier campus fascist organization whose activities consisted of organizing death threat campaigns and trying to get people fired over their political beliefs. Freedom of Speech” my ass.

Kirk argued for a new conservatism that advocated for freedom of speech, challenging Big Tech and the media, and centering working-class Americans beyond the nation's capital.
