gwern··on More Everything Forever
This also illustrates the bad research that goes into this sort of thing. There are no deep roots of 'TESCREAL' (which doesn't exist to begin with) in Russian Cosmism, because there are no roots of any of those ingredients separately in Russian Cosmism.

Stross just made that up, as pure post hoc ergo propter hoc. There are no sources, and he got it from Hannu: https://gwern.net/review/quantum-thief#fn2 Stross has chosen to never revisit the topic to try to substantiate his suggestion.

This quote winds up being rather exemplary: for example, that one parenthetical description manages to make at least 3 errors: 1. Fyodorov was born in 1823, so he obviously could not have invented anything in the '18th century' (ie. 1700s); 2. Cosmism included many things, not just the 'Great Common Task', and the Great Common Task itself went far beyond reviving ancestors, including many overall more important things like colonizing the entire universe or conquering death; 3. and further, the revival part was not about computer simulation at all (that's Hannu's _Quantum Thief_ fictional version of the idea that he came up with for his Sobornosts!) but reviving them physically, in the body, possibly using cloning - and was no more about "inside of a simulation" than Jesus reviving the dead was.

You're right that Hannu made great use of Cosmism as world-building in the Quantum Thief trilogy which I highly recommend (see my review above) - but that could only work because the ideas of Cosmism are so novel & exotic, and not part of Western transhumanism. If they really were as foundational as Stross claims, the 'taproot' of Western ideas, they would make about as exciting fictional worldbuilding as suggesting that you have some sort of 'laws' for AIs, starting with 'An AI may not injure a human being or, through inaction, allow a human being to come to harm."...

gwern··on The raccoons who made computer magazine ads great
If you mean https://i0.wp.com/technologizer.com/home/wp-content/uploads/... It's definitely a weird image. The hands are oddly accurate, and the geometry in the background is also unusually straight and correct for a low-end corporate 2024 Bing DALL-E or Stable Diffusion slop image. And in the bottom image, the food is way too sharp, and the sci-fi text UI is also way too accurate.

So I am suspicious something else is going on to produce the overall uncanny effect of wrongness: possibly they used Photoshop to paste on a bunch of unrelated images to some low-quality stock-art backgrounds?

gwern··on Algebraic Semantics for Machine Knitting
I suppose if nothing else, you could encode Wang tiles (https://en.wikipedia.org/wiki/Wang_tile) into knitting and then that's Turing-complete? Or would there be some better CA to encode?
gwern··on Dumb statistical models, always making people look bad
Yes, exponential smoothing in forecasting is another classic example of the robustness of simple models. You can throw all your fancy ARIMAs and Box-Cox transforms at a time-series, and much of the time, it is hard to distinguish from a simple moving average.

Specifically, the Makridakis M forecasting competitions (https://en.wikipedia.org/wiki/Makridakis_Competitions) have shown for a long time that beating the baselines is shockingly difficult.

In fact, classic machine learning only really started to convincingly win with the second-to-last, M5: https://www.sciencedirect.com/science/article/pii/S016920702... ; and neural methods only just sort of began working with the latest one, M6: https://www.sciencedirect.com/science/article/pii/S016920702... . (Possibly with M7 we'll see scaled-up meta-learning Transformers finally start beating the Bayesian or decision-tree forecasters. But I don't know if or when a M7 might be held.)

gwern··on Dumb statistical models, always making people look bad
> There are a few ways to look at this from the standpoint of information that is available to the decision-maker. One is that human knowledge is valuable for guiding developing the model, but once you have a statistical model, it’s a better aggregator of the information. This is echoed by research on judgmental bootstrapping (https://gwern.net/doc/statistics/decision/1974-dawes.pdf), where a statistical model trained on a human expert’s past judgments will tend to outperform that expert.

By the way, note that this applies to LLMs too. One of the biggest pons asinorums that people get hung up on is the idea that "it just imitates the data, therefore, it can never be better than the average datapoint (or at least, best datapoint); how could it possibly be better?"

Well, we know from a long history that this is not that hard: humans make random errors all the time, and even a linear model with a few parameters or a little flowchart can outperform them. So it shouldn't be surprising or a mystery if some much more complicated AI system could too.

gwern··on Why drinking coffee in Iran has become so complicated
Let me give you an example I just ran into now which illustrates why #1 is so pernicious.

I was just linked, by an intelligent, educated, skeptical person who regularly uses AI generative tools, to an interesting report on the darknet markets (which I used to be an expert on): https://tornews.org/legendary-darknet-vendor-crimsonlotus-ta... I was not familiar with this site, but I figured it was probably one of many successors to DeepDotWeb, and I've been out of the scene for a long time and wouldn't know about it; but I eventually realized, after several minutes of reading and then checking, that this was an AI slop website. This is because 'Obsidian Bay' doesn't appear to be real, the photo is obviously AI-generated, and the closing commentary by 'Ella Vargas, darknet researcher at the Cyber Crimes Institute' appears to be a fake person at a non-existent organization. Is anything in the article real? Probably not.

Ahhhhh, but you say you don't care about it being real, you say you only care about the prompt - in which case you're fine: some things in it are old events relabeled. (eg. there really was a large darknet market which was famous and had eluded LE and was taken down in a global operation in part due to packet timing attacks! You did learn something true from that accurate prompt/input yielding that slop output! It was just called 'Silk Road 2' and that happened over a decade ago.) So, I guess you have no issue with tornews.org. Maybe you should subscribe. All these articles sound quite exciting and there's a lot of them...

Personally, I think it's a bad site. I could have fallen for it - I simply got lucky that this one was so easy to note the style, factcheck, and debunk. For example, I could have instead read https://tornews.org/massive-dark-web-drug-operation-busted-i... : if you read this, this sounds very plausible and exciting, and it doesn't immediately come off as AI slop because it is so detailed and doesn't sound too much like 4o.

This, it turns out, is because it's based on a real bust: https://www.suffolkcountyda.org/suffolk-county-district-atto... https://www.newsday.com/long-island/fentanyl-bust-suffolk-k7... Heavily rewritten to obscure the sources being plagiarized. How much of it is real? Well, the assertions I spotchecked seemed to be real (ie. copied without too much distortion from the police press conference)... but I have no idea about the rest of it, and this article lends credibility to the other articles.

(Why does this week-old site exist at all and even has a Twitter account? https://x.com/tornews_org It's almost certainly either for the affiliate marketing revenue, in the best-case scenario, or is a phishing scam, in the worst-case scenario. Since it's so young and so reliant on fake content, likely the latter. I didn't check any of the onion links they so helpfully provide, but even if they are all legit right now, that simply means they are not yet scamming. To pay for the AI and domain name and labor here, you only need to phish one DNM user who will deposit a few hundred dollars of cryptocurrency. And this site has already started to pollute Google with its 'facts'.)

> It doesn't make any difference and doesn't invalidate my critique. It appears to be a science communication book, so it could easily be a web page. Even if it was a LaTeXish PDF there were multiple ways to not making it a PDF that resembles a scientific article, there's a precise choice being made about how to communicate. The medium is the message.

If this is really your response, I agree with your original comment about you being burned-out.

gwern··on Why drinking coffee in Iran has become so complicated
> What I can't figure out is why you seem so confident that the OP didn't verify the LLM output and/or would have published anything written by the model, whether it was faulty or not (which again, in this case it wasn't).

Because I routinely catch people, often very intelligent and educated people, confidently posting LLM materials that they have not factchecked and which are wrong (such as, say, about history, where they might make an argument about human evolution based on cave-dwelling where 4o was merely off by a few hundred thousand years), and I still find confabulations in my own use of even frontier models like o1-pro or Gemini-2.5-pro (leaving aside o3's infamous level of crimes, which I think is probably unrepresentative of reasoning models and idiosyncratic to it).

And in this case, the prompt looks like it was very low quality. The author had plenty of chances to put in details from his own real experience as an actual Iranian - any intelligent, observant college undergrad routinely buying coffee ought to have plenty to say - and instead, it's super-vague waffle that... well... an LLM could have written about just about any country, swapping out a few clauses. ("Why drinking coffee in America has become so complicated")

> You're clearly allergic to basic LLM-style

This is not a 'basic' LLM style. It is a very specific, recent chatbot style. (Note that visarga was able to instantly tell it was the recent 4o, because that style is so distinct compared to the previous 4o - never mind Claude-3, Gemini, Llama, Grok etc.)

Further, there should be no single 'LLM-style'; it makes me sad how much LLM writing capability has been collapsed and degraded by RLHF tuning. Even my char-RNN outputs from 2015, never mind GPT-3-base in 2020, showed more occasional sparks of flair than a 2023 ChatGPT did.

> or at least the masquerading of LLM text as human, so I'm curious what you'd consider worse: 1. LLM-generated text reflecting an accurate prompt/input, or 2. genuine human BS wanting to be taken seriously? (e.g. The Areas of My Expertise by John Hodgman if it wasn't in jest)

#1 is worse (if unedited/factchecked/improved etc and just dumped out raw), because there will be much more of it and the intermingling of fact and fiction makes it harder to factcheck, harder to screen out of future training corpuses, and overall more insidious. Human BS serves as costly proof-of-work and because it is costly, once you recognize you are reading BS from someone like Elon Musk or Sam Altman, you can switch modes and ignore the factual content and ask, 'why is he writing this? what purpose does this BS serve? who is the audience here and how are they using it?' and get something quite useful out of it. I have learned a lot from statements by humans where little or none of it was factually true. Whereas a LLM output may mean nothing more than 'some unattended code spent $0.0001 to spam social media with outputs from a canned prompt', if even that.

gwern··on Welcome to the Era of Experience [pdf]
> Why choose a format that resembles a published article instead?

...It is in a format that resembles a published article because it is going to be a published article? "This is a preprint of a chapter that will appear in the book Designing an Intelligence, published by MIT Press." on the first page.

> As for the graph, it’s too generic

A history of RL from DQN to AlphaProof/LLM computer use in Gemini is not 'generic', and could not be.

> it doesn’t provide any real value

It provides value to people who were not around then and not familiar with how RL attention peaks and crests, and a similar chart about TD-Gammon and Deep Blue, say, would likewise be useful for the many people who did not actually live through those eras, and helps contextualize material from back then. (I did, and maybe you did, and so it's not useful to us, but there exist other, younger people in the world, who are not us{{citation needed}}.) And the fact that these cycles exist is something worth reflecting on - Karpathy and others have reflected on how there were expectations of DRL leading to AGI in the 2015-2020 period, which wound up being swamped by self-supervised learning and DRL relegated to a backwater (and contributed very directly to many major events like how OA and DM became like they are now - and why Sutton is at Keen rather than DM with Silver), but now suddenly becoming super-relevant again.

gwern··on Falsify: Hypothesis-Inspired Shrinking for Haskell (2023)
The special value doesn't stand out, though. All three examples I gave were what I thought skimming his comment before my brain caught up to his caveat about an empty third argument. The empty string looked like it was by far the most harmless part... Whereas if they are all empty strings, then by definition the empty string stands out as the most suspicious possible part.
gwern··on Falsify: Hypothesis-Inspired Shrinking for Haskell (2023)
Really? Your examples seem the opposite. I am left immediately thinking, "hm, is it failing on a '!', some sort of shell issue? Or is it truncating the string on '#', maybe? Or wait, there's a space in the third one, that looks pretty dangerous, as well as noticeably longer so there could be a length issue..." As opposed to the shrunk version where I immediately think, "uh oh: one of them is not handling an empty input correctly." Also, way easier to read, copy-paste, and type.

> I don't know what the rest of your comment is talking about. Googling "Yirgacheffe" shows it's a real thing. The Safavid coffee/Qajar tea claims seem accurate as well. So you at least learned something from the article.

No, I didn't learn anything from the article (except how susceptible HN has become to even 4o-level LLM outputs, of course). I learned something from your comment, and you learned that from a Google search. Do you see the difference?

> So the actual content of the article is perfectly plausible.

So in other words... it added nothing to even a superficial familiarity with the topic.

gwern··on Welcome to the Era of Experience [pdf]
What fancy things? There's not a single equation in the whole thing. (I don't think this is even using Computer Modern, is it? It looks like a considerably thicker serif, and some of the characters like the lower-case 'g' look different.) Or are you referring to 'having 4 short, simple footnotes' as 'fancy' now? And also the graph makes perfect sense and tracks my own impression of RL history, what are you talking about?
gwern··on Computational Complexity of Air Travel Planning [pdf] (2003)
Since these sorts of things usually only get more and more complex over time, I would guess that it's all still true, but much more so.
gwern··on Why drinking coffee in Iran has become so complicated
They obviously did not write OP and 'just' machine translate it, because no one writes like that (and if they were being honest, they would have disclosed that upfront). A LLM came up with most of that... and maybe all of that... and how much of that is true? (What do you know about coffee in the Safavid era, or tea in the Qajars? Is 'Ethiopian Yirgacheffe' even a thing? Is there a coffee culture in Iran at all? How would you know? Only 1 or 2 commenters on this page even seem to know anything about Iran to begin with.)

> Seems like the same tired take on third wave coffee, without much specific to Iran.

> This article is a bit whiny about the new, and doesn't talk enough about the qualities of the old.

> Funny how even a repressive theocracy can seem so familiar. I guess that's globalization for you.

> One thing the author fails to take note of here is that Iranians have historically been extremely precious about their bougie little drinks.

> This is a poor take on what's actually a rich cultural shift towards variety seeking.

gwern··on Why drinking coffee in Iran has become so complicated
Bingo. OP is obviously LLM-written and is nothing but clickbait. (Did anything but that tweet even happen? Is any of it true?) And HN is falling for it hook, line, and sinker exactly as calculated.

Look at the author's previous blog posts: low effort, not even correctly spelled or written, like https://adelbordbari.github.io/album/2025-1-25-the-horror-an... (as expected from an Iranian ESL) - and then this one is suddenly boom: perfectly spelled, em-dashes all over, and where did all these <br> come from? Who writes a Github Pages Markdown Jekyll post with a bunch of <br>s in it...? An LLM, obviously.

gwern··on Walled Gardens Can Kill
> Apple should not be the arbiter...I would strongly oppose Apple unilaterally deciding which apps can-, and which cannot-, use the geofencing feature... Apple to restrict certain apps...but for them to do that on their own is completely out of line.

As opposed to all the other Apple decisions?

By the way, which law requires Apple to provide geofencing to a health insurance app such it can't even be installed outside a particular country, and ties its hands completely on the matter?

gwern··on Walled Gardens Can Kill
> This is really the fault of the insurance company (they geo-locked the app, Apple is just respecting that).

This sounds like a verbose way of saying "this is really the fault of Apple".

gwern··on What does it mean for a technology to follow Wright's Law?
> Most technologies do not follow Wright’s Law – the prices of bicycles, fridges, or coal power plants do not decline exponentially as we produce more of them.

I would bet Roser is wrong here and he can't provide a reference for his claims here. I'd predict that they do decline exponentially, it is just that (1) we have already produced a huge number of them so it's hard to observe the next doubling of cumulative production, and (2) the learning rate exponent is a lot worse than in the more obvious examples like solar panels or deep learning.

gwern··on Cursor IDE support hallucinates lockout policy, causes user cancellations
Who will be the first AI-first company to close the loop with autonomous coding bots, and create self-fulfilling prophecies where a customer support bot hallucinates a policy like OP, it gets stored in the Q&A/documentation retrieval database, and the autonomous bots implement and roll out the policy and lock out all the users (and maybe the original human developers as well)?
gwern··on Liquid: Language models are scalable and unified multi-modal generators
> For the first time, Liquid uncovers a scaling law that performance drop unavoidably brought by the unified training of visual and language tasks diminishes as the model size increases...No prior work has explored whether LLMs retain the power-law scaling laws observed in language tasks when extended to visual generation tasks. We prove this alignment and further show that vision can be effectively learned by LLMs as a form of language.

Does this really show much that https://arxiv.org/abs/2301.03728#facebook (uncited) and other earlier work did not?

gwern··on What can we take away from the ‘stochastic parrot’ saga?
It was not 'strictly philosophical' in the way some things like the Chinese Room argument are; in Chinese Room, it's stipulated that the Room is pragmatically capable of responding like a native Chinese speaker (it is somehow implemented super-fast and can chat in Mandarin with you and pass a Mandarin Turing Test).

However, the stochastic parrot arguments (and Gary Marcus in many of his writings) made specific, unambiguous empirical predictions about how LLMs would never be able to do many things, such as 'add numbers'. For example, in the original Bender & Koller 2020 paper "Climbing towards NLU: On Meaning, Form, and Understanding in the Age of Data" (which lays out the core ideas which are the justification for the 2021 paper that actually introduced the rhetoric of 'stochastic parrot') made many clear, falsifiable statements about what LLMs would never be able to do; here's one of them: https://aclanthology.org/2020.acl-main.463.pdf#page=14

> To get a sense of how existing LMs might do at such a task, we let GPT-2 complete the simple arithmetic problem 'Three plus five equals'. The five responses below, created in the same way as above, show that this problem is beyond the current capability of GPT-2, and, we would argue, any pure LM.

One could say many things about this claim, but not that it is a 'strictly philosophical one'.

gwern··on The Bitter Prediction
Well then - the cost of hiring a LLM compared to hiring a human is irrelevant if you are going to deny that hiring in general is irrelevant, now isn't it? So either OP is making an idiotic comparison because he is wrong and using a LLM to do programming already is several orders of magnitude cheaper than using a human to do programming and it is vastly more likely that poor people will be able to afford occasional LLM use, or it's idiotic because it's irrelevant.
gwern··on The Bitter Prediction
> Forty-six percent of the global population lives on less than $5 per day. In some countries, more than 90% of the population lives on less than $5 per day. If agentic AI code generation becomes the most effective way to write high-quality code, this will create a massive barrier to entry. Access to technology is already a major class and inequality problem. My bitter prediction is that these expensive frontier models will become as indispensable for software development as they are inaccessible to most of the world’s population.

Forty-six percent of the global population has never hired a human programmer either because a good human programmer costs more than $5 a day{{citation needed}}.

gwern··on The Manicule: The little hand that's everywhere
One of the frustrating things about the manicule is what I think is the reason you don't see it used online, and it is "everywhere" only in physical media: cluttered pages/GUIs and low-DPI screens mean that almost all of those manicules you see as scans just don't work as a digital manicule. It's always easier to use some sort of arrow or background highlight or other way of calling attention to a particular line. Note that OP makes no use of a manicule in this web page, and the only web example OP gives is an emoji - which was intended for SMS chat messages (and looks very ugly, even ignoring the color or other issues with emoji). That is probably why it is honored mostly in the breach by contemporary web designers - many more know about it than use it.

Like that gorgeous orange (letterpress, I assume) manicule you see in the middle of OP - that line-work will never work when scaled down and put into a web page as a normal little manicule. The details get lost in a blur, the hand becomes a solid blob of black, it looks goofy and out of place (note: for the mouse pointer, this is a feature, not a bug), or it ceases to look like a hand at all to someone who isn't primed for it by an article.

I can tell you that because I tried one that looked a lot like that. I went through literally hundreds of manicules from Wikimedia Commons, Font Awesome, Google Images, and articles like this, trying dozens of them on my actual website, and it took that long to find a single one I was at all happy with in context. I was shocked. No other icon I use on my site was that hard to find an adequate version of. (We really wanted a manicule for our use-case, so we persevered.)
