Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

Want to wade into the sandy surf of the abyss? Have a sneer percolating in your system but not enough time/energy to make a whole post about it? Go forth and be mid: Welcome to the Stubsack, your first port of call for learning fresh Awful you’ll near-instantly regret.

Any awful.systems sub may be subsneered in this subthread, techtakes or no.

If your sneer seems higher quality than you thought, feel free to cut’n’paste it into its own post — there’s no quota for posting and the bar really isn’t that high.

The post Xitter web has spawned soo many “esoteric” right wing freaks, but there’s no appropriate sneer-space for them. I’m talking redscare-ish, reality challenged “culture critics” who write about everything but understand nothing. I’m talking about reply-guys who make the same 6 tweets about the same 3 subjects. They’re inescapable at this point, yet I don’t see them mocked (as much as they should be)

Like, there was one dude a while back who insisted that women couldn’t be surgeons because they didn’t believe in the moon or in stars? I think each and every one of these guys is uniquely fucked up and if I can’t escape them, I would love to sneer at them.

(Credit and/or blame to David Gerard for starting this.)

Hey, remember Sabine Hossenfelder? The transphobe who makes YouTube videos? She published a physics paper! Well, OK, she posted a thing to the arXiv for the first time since January 2024. I read it, because I've been checking the quant-ph feed on a daily basis for years now, and reading anything else is even more depressing. It's vague, meandering glorp that tries to pretty up a worldview that amounts to renouncing explanation and saying everything happens because Amon-Ra wills it. Two features are worth commenting upon. The acknowledgments say,

I acknowledge help from ChatGPT 5 for literature research as well as checking this manuscript. I swear I actually wrote it myself.

"Tee hee, I shut off my higher brain functions" is a statement that should remain in the porn for those who have a fetish for that.

And what literature does Hossenfelder cite? Well, there's herself, of course, and Tim Palmer (one of those guys who did respectable work in his own field and then decided to kook out about quantum mechanics). And ... Eric Weinstein! The very special boy who dallied for a decade before writing a paper on his revolutionary theory and then left his equations in his other pants. Yes, Hossenfelder has gone from hosting a blog post that dismantled "Geometric Unity" to citing it as a perfectly ordinary theory.

If she's not taking Thielbux, she's missing an opportunity.

taking a bad paper too seriouslyHossenfelder starts her "Summary" section thusly:

I have shown here how the assumption that matter and geometry have the same fundamental origin requires the time evolution of a quantum state to differ from the Schrödinger equation.

This conclusion is unwarranted. It follows, not from the given assumption, but from the overcomplicated way that assumption is implemented and the kludges built on top of that. Here is how Hossenfelder introduces her central assumption:

What I am assuming here is then that in the to-be-found underlying theory, geometry carries the same information as the particles because they are the same. [...] Concretely, I will take this idea to imply that we have a fundamental quantum theory in which particles and their geometry are one and the same quantum state.

Taking this at face value, the quantum state of a universe containing gravitating matter is just a single ray in a Hilbert space. As cosmic time rolls on, that ray rotates. This unitary evolution of the state vector is the evolution both of the matter and of the geometry. There is, by assumption, no distinction between them. But Hossenfelder hacks one in! She says that the Hilbert space must factor into the tensor product of a Hilbert space for matter and a Hilbert space for geometry. And then she says that the only allowed states are tensor products of two copies of the same vector (up to a unitary that we could define away). If matter and geometry were truly the same, there would be no such factorization. We would not have to avoid generating entanglement between the two factors by breaking quantum mechanics, as Hossenfelder does, simply because there would not be two spaces to tango.

I am skeptical of this whole approach on multiple levels, but even granting the basic premise, it's a bad implementation of that premise. She doesn't have a model; she has a pathological "fix" to a problem of her own making.
