Need to let loose a primal scream without collecting footnotes first? 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.

Can we all take a moment to appreciate this absolutely wild take from Google's latest quantum press release (bolding mine) https://blog.google/technology/research/google-willow-quantum-chip/
The more I think about it the stupider it gets. I'd love if someone with an actual physics background were to comment on it. But my layman take is it reads as nonsense to the point of being irresponsible scientific misinformation whether or not you believe in the many worlds interpretation.
"Quantum computation happens in parallel worlds simultaneously" is a lazy take trotted out by people who want to believe in parallel worlds. It is a bad mental image, because it gives the misleading impression that a quantum computer could speed up anything. But all the indications from the actual math are that quantum computers would be better at some tasks than at others. (If you want to use the names that CS people have invented for complexity classes, this imagery would lead you to think that quantum computers could whack any problem in EXPSPACE. But the actual complexity class for "problems efficiently solvable on a quantum computer", BQP, is known to be contained in PSPACE, which is strictly smaller than EXPSPACE.) It also completely obscures the very important point that some tasks look like they'd need a quantum computer — the program is written in quantum circuit language and all that — but a classical computer can actually do the job efficiently. Accepting the goofy pop-science/science-fiction imagery as truth would mean you'd never imagine the Gottesman–Knill theorem could be true.
To quote a paper by Andy Steane, one of the early contributors to quantum error correction:
Tangentially, I know about nothing of quantum mechanics but lately I've been very annoyed alone in my head at (the popular perception of?) many-world theory in general. From what I'm understanding about it, there are two possibilities: either it's pure metaphysics, in which case who cares? or it's a truism, i.e. if we model things that way that makes it so we can talk about reality in this way. This... might be true of all quantum interpretations, but many-world annoys me more because it's such a literal vision trying to be cool.
I don't know, tell me if I'm off the mark!
Unfortunately "states of quantum systems form a vector space, and states are often usefully described as linear combinations of other states" doesn't make for good science fiction compared to "whoa dude, like, the multiverse, man."
