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.
(Credit and/or blame to David Gerard for starting this.)
Deep thinker asks why?
Thus spoketh the Yud: “The weird part is that DOGE is happening 0.5-2 years before the point where you actually could get an AGI cluster to go in and judge every molecule of government. Out of all the American generations, why is this happening now, that bare bit too early?”
Yud, you sweet naive smol uwu baby
esianboi, how gullible do you have to be to believe that a) tminus 6 months to AGI kek (do people track these dog shit predictions?) b) the purpose of DOGE is just accountability and definitely not the weaponized manifestation of techno oligarchy ripping apart our society for the copper wiring in the walls?very late response but this is very funny because Yud made a post about AGI being a meaningless term and you shouldn’t say things like “we have achieved AGI!” and then he turns around and posts this….why??? pick a lane man
bahahahaha “judge every molecule.” I can’t believe I ever took this guy even slightly seriously.
The worst part is I can’t tell if that’s not meant to be taken literally or if it is.
He retweeted somebody saying this:
The cheat code to reading Yudkowsky- at least if you’re not doing death-of-the-author stuff- is that he believes the AI doom stuff with completely literal sincerity. To borrow Orwell’s formulation, he believes in it the way he believes in China.
Yud be like: "kek you absolute rubes. ofc I simply meant AI would be like a super accountant. I didn’t literally mean it would be able to analyze gov’t waste from studying the flow of matter at the molecular level… heh, I was just kidding… unless 🥺 ? "
“judge every molecule” and “simulation hypothesis” probably have a bit of a fling going
“The AI is attuned to every molecular vibration and can reconstruct you by extrapolation from a piece of fairy cake” is a necessary premise of the Basilisk that they’ve spent all that time saying they don’t believe in.
Quantum computing will enable the AGI to entangle with all surrounding molecular vibrations! I saw another press release today
Interesting slides: Peter Gutmann - Why Quantum Cryptanalysis is Bollocks
Since quantum computers are far outside my expertise, I didn’t realize how far-fetched it currently is to factor large numbers with quantum computers. I already knew it’s not near-future stuff for practical attacks on e.g. real-world RSA keys, but I didn’t know it’s still that theoretical. (Although of course I lack the knowledge to assess whether that presentation is correct in its claims.)
But also, while reading it, I kept thinking how many of the broader points it makes also apply to the AI hype… (for example, the unfounded belief that game-changing breakthroughs will happen soon).
The attitude to theoretical computer science re quantum is really weird. Some people act as if “I can’t run it now therefore it’s garbage” which is just such a nonsense approach to any kind of theoretical work.
Turing wrote his seminal paper in 1936, over 10 years before we invented transistors. Most of CS theory was developed way before computers were proliferated. A lot of research into ML was done way before we had enough data and computational power to actually run e.g. neural networks.
Theoretical CS doesn’t need to be recent, it doesn’t need to run, and it’s not shackled to the current engineering state of the art, and all of that is good and by design. Let the theoreticians write their fucking theorems. No one writing a theoretical paper makes any kinds of promises that the described algorithm will EVER be run on anything. Quantum complexity theory, for example was developed in the nineties, there was NO quantum computer then, no one was even envisioning a quantum computation happening in physical reality. Shor’s algorithm was devised BEFORE THAT, before we even had the necessary tools to describe its complexity.
I find the line of argumentation “this is worthless because we don’t know a quantum computer is engineeringly feasible”
- Insulting,
- Stupid,
- Lacking whimsy,
- Unscientific at its core.
He’s right that current quantum computers are physics experiments, not actual computers, and that people concentrate too much on exotic threats, but he goes a bit off the rails after that.
Current post quantum crypto work is a hedge, because no-one who might face actual physical or financial or military risks is prepared to say that there will be no device in 10-20 years time that can crack eg. an ECDH key exchange in the blink of an eye. You’ve got to start work on PQC now, because you want to be able subject it to a lot of classical cryptanalysis work because quantum-resistant is no good by itself (see also, SIKE which turned out to be trivially crackable).
The attempt to project factorising capabilities of future quantum computers is pretty stupid because there’s too little data to work with, so the capabilities and limitations of future devices can’t usefully be guessed at yet. Personally, I’d expect them to remain physics experiments for at least another 5-10 years, but once a bunch of current issues are resolved you’ll see rapid growth in practical devices by which time it is a bit late to start casting around for replacement crypto systems.
Yeah, that’s also something I found oddly missing (i.e. that replacing crypto systems world wide, if it becomes necessary, will take a very long time).
It’s been frustrating to watch Gutmann slowly slide. He hasn’t slid that far yet, I suppose. Don’t discount his voice, but don’t let him be the only resource for you to learn about quantum computing; fundamentally, post-quantum concerns are a sort of hard read in one direction, and Gutmann has decided to try a hard read in the opposite direction.
Page 19, complaining about lattice-based algorithms, is hypocritical; lattice-based approaches are roughly as well-studied as classical cryptography (Feistel networks, RSA) and elliptic curves. Yes, we haven’t proven that lattice-based algorithms have the properties that we want, but we haven’t proven them for classical circuits or over elliptic curves, either, and we nonetheless use those today for TLS and SSH.
Pages 28 and 29 are outright science denial and anti-intellectualism. By quoting Woit and Hossenfelder — who are sneerable in their own right for writing multiple anti-science books each — he is choosing anti-maths allies, which is not going to work for a subfield of maths like computer science or cryptography. In particular, p28 lies to the reader with a doubly-bogus analogy, claiming that both string theory and quantum computing are non-falsifiable and draw money away from other research. This sort of closing argument makes me doubt the entire premise.
Thanks for adding the extra context! As I said, I don’t have the necessary level of knowledge in physics (and also in cryptography) to have an informed opinion on these matters, so this is helpful. (I’ve wanted to get deeper in both topics for a long time, but life and everything has so far not allowed for it.)
About your last paragraph, do you by chance have any interesting links on “criticism of the criticism of string theory”? I wonder, because I have heard the argument “string theory is non-falsifiable and weird, but it’s pushed over competing theories by entrenched people” several times already over the years. Now I wonder, is that actually a serious position or just conspiracy/crank stuff?
All attempts to make a theory of quantum gravity are unfalsifiable, because the relevant experiments are far beyond our means, much further so than building a practical quantum computer. String theory benefited from multiple rounds of unexpectedly interesting mathematical discoveries, which fired up people’s hopes and kept the fires burning. None of the other assorted proposals (loop quantum gravity, asymptotic safety, …) got lucky like that. Moreover, there’s a case to be made that if you’re an orthodox quantum field theory researcher, any attempt you make to quantize gravity will end up a string theory. Roughly speaking, there’s no regime in which gravity is the only force that you need to consider, so to make any predictive statements about some quantum gravity effect, you need to understand all the physics that happens at energy levels in between “warm summer day” and “immediate aftermath of the Big Bang”. String theory was the only possibility that suggested there could be a way out.
You could say that this just goes to show that orthodox QFT specialists lack imagination. The pioneers of quantum theory devised it in order to explain hot gases in glass tubes. Why should their same notions about what it means to “quantize” also apply to space and time themselves? And maybe they don’t! But proposing an alternative to quantum mechanics, or a modification of quantum mechanics that works in all the circumstances where we have already confirmed quantum mechanics, is no easy task.
“Fundamental” physics had a period of great advances, from the 1890s with the discovery of X-rays and radioactivity through the early 1970s with the establishment of the Standard Model. From then, we’ve been in “the stall”, as barbecue folks say. The big accelerators have filled in the edges of the picture and confirmed some predictions from that era, like finding the top quark and the Higgs. But they have yet to deliver a sign of beyond-Standard-Model physics that holds up under scrutiny.
Oh wow, thank you for taking the time! :)
Just one question:
None of the other assorted proposals (loop quantum gravity, asymptotic safety, …) got lucky like that.
Is this because the alternate proposals appeared unpromising, or have they simply not been explored enough yet?
It’s conceivable that there was some amazing math lurking in one or more of the non-string-theory ideas, and nobody was lucky enough to find it.
The sibling comment gives a wider perspective. I’m going to only respond narrowly on that final paragraph’s original point.
String theories arise naturally from thinking about objects vibrating in spacetime. As such, they’ve generally been included in tests of particle physics whenever feasible. The LHC tested and (statistically) falsified some string theories. String theorists also have a sort of self-regulating ratchet which excludes unphysical theories, most recently excluding swampland theories. Most money in particle physics is going towards nuclear power, colliders like LHC or Fermilab’s loops, or specialized detectors like SK (a giant tank of water) or LIGO (artfully-arranged laser beams) which mostly have to sit still and not be disturbed; in all cases, that money is going towards verification and operationalization of the Standard Model, and any non-standard theories are only coincidentally funded.
So just by double-checking the history, we see that some string theories have been falsified and that the Standard Model, not any string theory, is where most funding goes. Hossenfelder and Woit both know better, but knowing better doesn’t sell books. Gutmann doesn’t realize, I think.
Thank you!
Never got too deep into Hossenfelder, but I gradually got the impression that Woit was taking a bit of an online-influencer tack, even starting before influencers were really a thing. The whole “not even wrong” flap seemed to draw in people who wanted to have strong opinions about high-energy physics and string theory without really studying them in any detail.
