    I don't think "judge writing by its quality instead of its source" is coherent. Certainly, the value of reading is in the thoughts it produces in the reader's mind. So if you want me to ignore the source, you're asking me to value the thoughts I get from the writing without regard for the thoughts that produced it. This seems dubious, if not actually oxymoronic. As a reader, it feels much like you telling me to eat something you made, which you enthusiastically assure me is high quality, but which you can't be bothered to eat yourself, and in fact you've never eaten anything like it before. Plus it smells like spray-cheese.

      The archaeological record is loaded with texts of dubious or unknown authorship. Many of our oldest classical texts fall into this category [1].

      That doesn't make them "oxymoronic" to engage with. Just more difficult. From a time when few were writing and fewer of their works survived, this is worth the effort. When a nickel of electricity can produce text, it's not–we need the filter of authorship to decide how much effort we, as humans, should expend in engaging.

        Are you trying to argue that archeological texts weren't written by humans? Because otherwise I don't understand how your comment is related to the parent comment. It has nothing to do with not knowing the identity of the author. It's about the author being a human.

          > trying to argue that archeological texts weren't written by humans?

          I’m arguing they’re minds of unknowable foreignness to our own. We fill in the gaps because the text per se has meaning. If anything, we give those minds meaning through the text, not the other way around.

          We impute “the thoughts that produced” those writings. One can just as easily contemplate the method through which human writing got distilled into a matrix of numbers that produced a particular output in response to a prompt.

          (I’ve absolutely read works without a care in the world for the author.)

            If anything, difference in mind is a reason to read. I want to know what experiences the other person has had which contribute to their perspective. No less so in areas like technical writing where perspective may be less overt.

          In Jorge Luis Borges's short story "Pierre Menard, Author of the Quixote" we learn that Menard, the fictional 20th century writer of the eponymous title, immerses himself in the language and culture of 16th century Spain (pre-1602, to be precise), to the point where he writes a chapters of a book which are word-for-word identical parts of Don Quixote.

          Yet the literary criticism of Borges's short story points out how the two texts have different messages.

          For Cervantes, this is a book for the people, written in the language of the people.

          For Menard, this is a book for specialists, who would understand the old Spanish language.

          In the 20th century of Bertrand Russell and William James, the philosophical concepts that an educated writer like Menard would know are far different than 16th century Spain, so an expression like "history, the mother of truth" has different meanings.

          Since you mention Homer, if I were to write of the wine-dark sea you would know I am referring to Homer. It brings along cultural connections, including its own Wikipedia page.

          While when Homer uses it, it doesn't have those connections.

          The idea that a text stands alone is a formalist style known as New Criticism, https://en.wikipedia.org/wiki/New_Criticism .

          > New Criticism developed as a reaction to the older philological and literary history schools of New England, which focused on the history and meaning of individual words and their relation to foreign and ancient languages, comparative sources, and the biographical circumstances of the authors, taking this approach under the influence of nineteenth-century German scholarship. The New Critics felt that this approach tended to distract from the text and meaning of a poem and entirely neglect its aesthetic qualities in favor of teaching about external factors. ...

          > It was frequently alleged that the New Criticism treated literary texts as autonomous and divorced from historical context, and that its practitioners were "uninterested in the human meaning, the social function and effect of literature."

          Borges's story is a commentary about this debate.

          While the linked-to essay in the Chronicle made no mention of the long discussion of the relevant literary theories, seemingly insisting that analytical writing somehow stands outside that debate, by simply ignoring the debate.

            One of my favorite New Criticism corollaries is that an author, after a work has been published, is not in a privileged position from which to speak on its meaning. Tolkien qua author is omnipotent. Tolkien qua post-publication commenter is another speaker, albeit a highly knowledgeable one. (Purposely picking an example where the author re-wrote his works after publication, e.g. retconning the Ring into The Hobbit.)

              That's a line which was more appropriate in a era before the majority of novels had sequels. Now we read series where the plot extends across multiple books. Events in earlier books set up situations to be resolved in later books.

              For a recent controversy in this area, ask Google "Is Dumbledore gay?"

                > a line which was more appropriate in a era before the majority of novels had sequels

                Serialisation pre-dates the novel.

                There is a legitimate debate around the degree to which an author can amend canon with sequels. Various fandoms reject sequels in literature and film, as is their right. I think the broad consensus tends towards treating sequels as canon, however.

                > For a recent controversy in this area, ask Google "Is Dumbledore gay?"

                Did Rowling write a sequel with this? I thought it was scrawled into the margin of a screenplay.

                I think you have to reject the text of the books to argue Harry Potter is an alien. You don’t necessarily to accept or reject Dumbledore’s sexuality.

                Which leads to some very strange standardized test questions where the students are supposed to use close reading - a New Criticism approach - to infer the author's intent, when what they are actually supposed to do is infer what the test authors consider to be the author's intent.

                https://curmudgucation.blogspot.com/2019/05/the-writer-who-c...

                > Back in 2017, Holbrook wrote an essay for Huffington Post entitled, "I Can't Answer These Texas Standardized Test Questions About My Own Poems." The writer had discovered that two of her poems were part of the Texas STAAR state assessment tests, and she was a bit startled to discover that she was unable to answer some of the questions.

                > One reason was simple inaccuracy. One question asked why the poet had inserted a stanza break in a particular spot-- and then didn't insert a stanza break in the testing materials. But there was a second issue. Holbrook is a performance poet, and she had inserted the break at the point where, in live readings, she pauses. That choice was not one of the choices available on the test.

                > In fact, much of Holbrook's issue with the questions was a sort of existential dilemma. Several questions asked, directly or indirectly, for the test taker to judge the author's intentions. The author knew some of her intentions, sort of remembered others, and had others that were layered and complex. But the manufacturers of the test--who had never asked her about any of this--provided only four choices that did not allow her to choose the answer that she knew to be correct.

                This leads to questions like: Is the author more or less privileged than the test writers? Are the test writers more or less privileged than the students taking the test? If they are of equal privilege then how can there be a standardized test concerning the author's intent?

                ...I'm not sure if you're agreeing with me? The identity of the author is not germane to my point, only whether there actually is an author, aka an actual mind. You could argue those old texts are worth engaging with exactly because they're our only links to those minds.

                • JumpCrisscross 2 hours ago

                  > whether there actually is an author, aka an actual mind

                  The mind is long dead. In true Cartesian form, we assume it existed. But it may not be, as with Homer, a single mind.

                  One can engage with text on its own. Even find meaning in it. Being unable and refusing to are separate categories.

                • eli_gottlieb 2 hours ago

                  Ok, but when you're reading Homer or Socrates or the Bible (we're relatively sure it has several different authors), you're still engaging with a communal tradition of fellow readers who, in large part, define what it actually means to understand the text. If you read the Odyssey and decide it was actually about Pokemon, you're misreading it.

                  • JumpCrisscross 2 hours ago

                    > you're still engaging with a communal tradition of fellow readers

                    Inasmuch as you’re reading translations upon translations, sure. But none of that is necessary.

                    (One could credibly argue that engaging with an LLM is engaging with, in a sense, its training corpus.)

                    > If you read the Odyssey and decide it was actually about Pokemon, you're misreading it

                    If you can stand by your reading based on the text, I say go for it. It doesn’t work in your example. But there are plenty of cases where what was once an against-the-grain interpretation dived into and out of the mainstream.

            • cosmic_ape 51 minutes ago

              I would go even further, and say that the idea that an academic paper should be readable by humans in 2026 is strange. The abstract and the introduction should be. The rest of it, as a reader, I can extract by talking to an LLM and asking what goes on in the paper.

              I have reviewed tens of papers this way by now, and one thing I'm certain of is that I get much better understanding of the paper this way. This does not save me time usually. If anything, I now spend more time reviewing a paper, but when I'm done I know more about the paper and if I need to provide feedback, it is more substantial.

              I would still prefer the abstract and the intro to be written for humans, as a sanity check. But whether the authors pored over every word, every word is "theirs" does not seem to matter much. If the ideas are good they are good, and if they are bad good writing is not a way to compensate.

              Two additional observations here:

              * That separation of high level and technical content is not new. Conference papers for a long time now are limited to ~9 pages and Appendix, and it was a well known secret that no one ever reads the Appendix, which contained all proofs, for instance (for all practical purposes. and I did read parts, for the record). Up to now that is, now we do read it again with LLM. No point not to do it.

              * There may be a finer point of whether one can separate the ideas from the language used to convey them. But I think it can, and again, we did it for a long time with the appendices.

                I want to hear directly from the finest minds humanity has to offer. When I want something from AI, I'll ask AI myself. In short, I want to know when something is human-authored vs. AI-authored. It really matters to me and I suspect to others too.

                • michaelt 57 minutes ago

                  While I broadly agree, I'm sympathetic to making some use of using AI when writers with an intermediate command of English are publishing papers in English.

                  Because, as a German academic once explained to me (years before the rise of LLMs), if you want your ideas to be influential you need people to read your papers, and you get a heck of a lot more readers when publishing in English than you do publishing in German.

                  Unfortunately, it's much more difficult to draw a clear line once you start allowing some AI writing tools.

                  • busssard 1 hour ago

                    are papers really still something to be consumed by humans though?

                    Papers themselves become a source, something to check back on. They dont write themselves, it takes significant effort to make a high quality paper even with the help of AI.

                    And if you write a review paper that is a needed piece of literature, but this is also something that can be perfectly digested by a well crafted paper harness. and review hundreds of papers in the time you review 3.

                    what is it going to be? Speed of scientific progress or human crafted prose?

                  • glimshe 2 hours ago

                    Many people here complain that AI writing is bad. And I agree with it, AI writing is boring and its distinctive tone is now associated with unpleasant thoughts for most people including me.

                    But I'm curious about how people will feel when AI writing is good and impossible to differentiate from a decent journalist-level writer, including with tooling. Then what? Are people going to stop reading?

                    I'm trying to separate the part of the argument related to "this writing is bad" from "this was written by AI".

                    I personally don't care if AI is a writing instrument for a human who's signing off on the content, as long as the writing is good and the source is legitimate.

                      The fundamental problem with most AI "writing" is that writing is a communication medium, and if your text was just generated by a prompt, I would always rather read the prompt than the output, as the output contains zero additional bits of information.

                      • jampekka 1 hour ago

                        When I write using LLMs, each paragraph may have dozens of iterations. The prompt is a lot longer than the resulting text and probably not really understandable. I'm sure nobody would want to read those prompts.

                      • lubujackson 1 hour ago

                        The comparison to painting before and after photography was invented is the closest to how I think about writing before and after AI.

                        We remember museum-quality painting, but there was a whole economy built around people getting portraits done. It was time-consuming and expensive. Then the camera came along and completely met that need with a far superior result (an accurate portrait) while being much cheaper and faster. So too has the listicle writer all but gone extinct.

                        But what about art? Painting went in a wild new direction, exploring the medium in a direct counter-trend from portraiture. In the same way, I expect "literary" and "experimental" writing become more outlandish while those middle of the road beach romance novel authors will shrivel up completely or flatten the market into a endless flood of options, possibly self-guided by readers.

                        The most interesting is what happened to photography, which quickly became its own art. Just as preposterous as saying prompting LLMs could be a form of artistic expression, photography was totally dismissed at first. But photography requires a much different skill set and type of discipline, while relying on the same visual concepts as painting.

                        If entire novels are going to be generated by AI, someone needs to write that prompt. What will it say? What concept will lead to a bestseller? This may seem reductive in extreme, but it puts a similar focus on the remaining human choices. If photos or prompts are relatively cheap, the expression of art becomes one of curation, instead of creation. Flower arranging and DJing are both curation and both expressive.

                          This is the question I keep asking the people who seem to really hate AI. At some point it will produce good writing, both fiction and non-fiction, and then what? Will people stop reading?

                          Someone commented over the weekend they had an LLM generate a sci-fi short story and their community loved it until they told them it was LLM generated.

                          I’ve also noticed a new type of ad-hominem attack (especially here on HN) where instead of engaging with an argument, people claim a comment is AI and move on. HN users have found 10 of the last 2 LLM generated posts.

                          This is such a great topic. On one hand academics writings are by default seen as original and a work of deep research. Unique voice of writers adds to the originality.

                          On the other hand AI can really be a good editor and give a final polish. But this path is fraught with danger as eventually "Editor" might turn into a "Writer"

                          This is something like handcrafted leather bag, quality assurance of parts like zips are okay but value lies in the craftsmanship rather than industrial production.

                          Another point is if writing can be done by AI, so can peer review. Then 100s of agents are just reviewing it and no real exchange of thoughts or ideas are happening. That, I feel would be a sorry state to be in

                            Nah. The value is in the branding.

                            There was an embarrassment a few years ago when it was discovered that one maker of fake Rolex watches was using the same movements as the branded version.

                              Agreed and my point is "hand crafted" itself is a "branding" and the marketing around "limited" edition and not mass produced add to the allure.

                              Regarding fakery I think even "Monalisa" could be faked that is inseparable from the original. We hear so many fake paintings are sold for million dollars after all the due diligence by experts. Nothing is sacrosanct against deliberate fakery but the demand and the allure of the original remain for the aficinados.

                            Well, the problem I have with this is that I'm paying academics. At the point where they're a proxy between my money as allocated by the government and an AI provider, I no longer wish to pay them. I am capable of paying the AI provider myself. I'm not upset about the output being what it is. That's fine. I just don't care so much about the being wishing to be paid to intermediate me and the machine I am fully capable of prompting without the aid of a professional hand-holder.

                            > That is why the model needs far more instruction to write than to code. I deploy it for its strengths and am constantly on alert for its weaknesses, which is what makes it a tool and not a ghostwriter.

                            Everyone is convinced of these grand truths - that they alone have contributed something of value to the machine work. But that value is extractable by almost anyone who interrogates the machine.

                            Like everyone else alive, I too believe this is monocausal. This is all a problem caused primarily by a distinction between the one who sees the supposed benefit of the academic (therefore induced to pay) and the one allocating resources to the academic. It is time we remove this intermediary who does this. Should you desire to read analytical writing by a professional machine speaker there is no doubt he will gladly take your money to talk to the AI for you. Let there be a market for academia - the mathematicians can be paid for the beauty they wish to glimpse between coffees and the philosophers can prompt their machines for money.

                            For the rest of us, release us from this compulsory taxation so that the plumber - should he so desire - can ask Fable 5.1 "Why should I pay academics to use AI to write?" and receive a satisfactory answer without needing to pay out of his taxes a compulsory fee for an answer to a question he may never desire to ask.

                              You seem to assume a case where academics write papers by single shotting from one prompt. Of course such papers are useless, but this is not how I at least use LLMs to write. I iterate the text in thousands of turns. I do tend to type all the final text in the manuscript too, sometimes editing it in the process. My current manuscript's session has about about 50k input tokens by me in about 1.6k individual messages. The manuscript currently is about 8k words (11k tokens). In total the session has about 50M tokens.

                              One frustrating, and very inefficient, part of the (lack of) division of labour in academia is that everyone has to write. And academic text has very particular format and demads, and writing it is a skill of its own. It's like asking that every software dev should be also be technical writers and write production level user manuals and ad copys on top.

                              And a lot more things than the writing goes into the paper. Designing, implementing and conducting the experiments. Studying, visualizing and analyzing the data. Interpreting the results in light of theory and previous literature. None of these require writing in the sense of writing a paper.

                              I would be ecstatic, and be a lot less wasteful in spending grant money, if I could stop wasting time writing the research in papers, and instead dump a git repo with some READMEs. But at least for now I have to also write the papers, but with LLMs maybe at 2x speed and with a lot less bad output.

                                There are heaps of problems with academia, and poor writing is just one of them. It existed pre AI. Whoever produced slop pre-AI now produces more of it. The good ones still stand out.

                                  Me. Because I used to love reviewing conference papers and AI has utterly ruined it.

                                  If the end result was reliably good people wouldn't be hating on it, but the vast majority of people are using AI not to elevate their output quality, but to churn out slop quantity, because that's where the incentives push them.

                                  Anyone who actually engages with the output can tell that the speedups you get on producing good prose, maintainable codebases or high quality abstractions are much much less because you can't let the LLM go brrr, so AI output tends to be drivel, and banning it is a good way to prefilter.

                                  It'd the same reason journals and conferences desk reject you if you don't follow their formating rules or don't use their template - it's a price of admission that ensures some consistent quality level, and if you couldn't be bothered to learn how to follow the rules, why should we trust you that the content is worth out time?

                                    If AI wrote it, it's not your voice. If you can't communicate your thoughts then it reflects a lack of clarity on you as the author. If you lack the clarity, AI assisted anything is probably part of the problem.

                                    If connecting with the audience and guiding them to understand your thoughts is irrelevant, then you are missing the point of writing and being an academic.

                                    There is a reason AI slop is revolting to read. It doesn't care.

                                    Why do you need academics then? Just ask the question to the LLM directly.

I worked on it with Claude Fable 5.1 and other large language models, as I now work on nearly everything, but I reviewed every line and rewrote most of them. By draft 10, I could not have said where the machine’s contribution stopped and mine began.?"

                                            ...

                                            -----------------

                                            If you read a lot of journal articles, you're probably accustomed to occasionally running into articles a ways outside your bailiwick that are written poorly, you don't really understand, which you suspect made it past reviewers who didn't really understand, and indeed, you suspect the authors didn't really understand. Everyone involved just gave them the benefit of the doubt because they were too busy to figure out what the tortured language really meant. However, you don't know for sure, so you decide to leave it up to people in that particular field to deal with.

                                            I can't speak for others, but I find AI writing to be frequently similar in its effect on me to bad writing. Yes, the grammar is correct, but it beats around the bush and puts emphasis on the wrong things. Even if you filter Claude through a human, those poor choices tend to shine through. This subtly inhuman voice switches your brain off. I suspect a lot of bad science is going to slip past reviewers because of LLM writing, and a lot of good science is going to slip past those who might need to read it, because the LLM co-written article switched their brains off and failed to make itself understood.

                                            I understand the notion that, if the content is good enough, it shouldn't matter if the article is written poorly or co-written with AI. However, if the content is good enough, isn't it worth communicating it well?

                                              Good point about emphasis. Correctness in emphasis, and I do mean correctness, was already underrated. It's a critical measure of whether you actually understand a topic, and an indicator of values in general.

                                              I am on two program committees for major CS conferences this year.

                                              LLM writing is horrible, full stop. The vast majority of papers that I see with obvious LLM writing ticks are also frankly incomprehesible. Claude's biggest sin at the moment is inventing new terminology (sometimes multiple times in a single sentence!) without stopping to explain what it means.

                                              In previous years, I would see a substantial fraction (maybe 30-50%) of papers that were obviously written by non-native English speakers, and full of grammatical mistakes and typos. I have seen zero papers like that this year. Honestly, I preferred those: reading LLM writing is painful by comparison.

                                              So far I have seen exactly one paper that had obvious LLM writing ticks, and yet had gone through enough passes (either of the LLM or the human authors) that the paper itself was comprehensible. So I'll admit that it's possible to do. But based on what I've seen this is vastly in the minority.

                                              I honestly used to enjoy the review process; even when the papers were bad at least I could usually see the effort that went into it and give some constructive guidance on how to improve. The process is dramatically less pleasant now, and it's not obvious if I'm accomplishing anything: if authors who write with LLMs just stick the reviews back into those same LLMs, will they learn anything? I suspect not.

                                              Maybe some day LLMs will be good enough to write, but as of today: please, please, just don't do it. The typos and grammatical mistakes are easier to read than the slop.

                                                That's a classic problem with academic writing. There are too many papers where, after you finally figure out what they're trying to say, you realize they didn't have much to say. Relevant XKCD: [1]

                                                What we seem to be getting from LLMs is more words per unit of useful knowledge. I wonder if academic papers are now bloated to allow for more ad slots. Many web sites with semi-academic content throw in an ad in the middle of the text every screen height or so. It's beneficial to the publisher if the author is wordy.

                                                The same problem now plagues AI-generated videos, especially the pseudo-historical ones bloated to allow for more YouTube ad slots. These videos have a consistent structure. About 15% into the video, there will be something like "we have to go back to", followed by a large insert of filler material. Around the 50% mark, the relevant content starts. Around the 80% mark, the topic has been covered and there's some general blithering to conclude.

                                                It's enough to make one long for the days of the neckbeard talking head with the big microphone.

                                                  I left academia before the AI craze, but I think the answer is the same as for any other type of author/reader relationship: many human readers care! Because writing human prose is almost always an endeavor in communication from a human to a human.

                                                  Many readers want to read the thoughts of the author. Filtered only by the author.

                                                    I'm fine with using AI for code, where the quality will likely be better than those of academics.

                                                    But writing.. FFS everything I see is just AI slop. And I only realize when I start wondering why the paper is going and going and saying nothing, and then pangram tells me that everything past the intro is just AI. :/

                                                    I care more if work is reproducible. Most academics articles are "trust me bro, I am scientist", no source data, no scripts used to process them. With AI I would expect publication of prompts and harness settings.

                                                        To be honest, people overvalue human writing too much. Even in academic research, there were quite a lot of cases where the writing was strange. I actually think AI writing is more readable, to that extent. People sometimes compare AI writing with the very best of human writing, but considering that AI writing is above average, I think it’s readable enough.
