    This would be true if chomskys claim was that he was simply studying human language acquisition and that machines are different, but his claim was that machines canā€™t learn human languages because they donā€™t have some intuitive innate grammar.

    Saying an llm hasnā€™t learned language becomes harder and harder the more you talk to it and the more it starts walking like a duck and quacking like a duck. To make that claim youā€™ll need some evidence to counter the demonstrable understanding the llm displays. Chomsky in his nytimes response just gives his own unprovable theories on innate grammar and some examples of questions llms ā€œcanā€™t answerā€ but if you actually ask any modern llm they answer them fine.

    You can define ā€œlearningā€ and ā€œunderstandingā€ in a way that excludes llms but youā€™ll end up relying upon unprovable abstract theories until you can come up with an example of a question/prompt that any human would answer correctly and llms wonā€™t to demonstrate that difference. I have yet to see any such examples. Thereā€™s plenty of evidence of them hallucinating when they reach the edge of their understanding, but that is something humans do as well.

    Chomsky is still a very important figure and his work on politics with manufacturing consent is just as relevant as when it was written over 20 years ago. His work on language though is on shaky grounds and llms have made it even shakier.

      Do you really think Chomskyā€™s UG hypothesis from half a century ago was formulated to deny that some dumb mathematical model would be able to simulate human speech?

      Almost nothing youā€™ve written has any grounding in empirical reality. You have a sentence that reads something like ā€œthe more you talk to LLMā€™s the harder it is to deny that they can use and understand language.ā€

      You might as well say that the longer you stare at a printed painting, the harder it is to deny that printers make art. LLMā€™s do not ā€œunderstandā€ their outputs or their inputs. If we feed them nonsense, they output nonsense. Thereā€™s no underlying semantics whatsoever. An LLM is a mathematical model.

      I know it looks like magic, but itā€™s not actually magic. And even if it were, it would have nothing to do with linguistics, which is concerned with how humans, not computers, understand and manipulate language. This whole ridiculous conversation is a non-sequitur.

        You are like, science denial-ism level of ignorance when it comes to this conversation, or perhaps, it might be that you donā€™t actually understand the underlying philosophy of scientific inquiry to understand why LLMs basically were able to break the back of both UH and innate acquisition.

        You seem like the kind of person who cheer-leads ā€œin the spirit of scienceā€ but doesnā€™t actually engage in it as a philosophical enterprise. You didnā€™t seem to notice the key point that @[email protected] made, which is that unlike UG, LLMā€™s are actually testable. Thatā€™s the whole thing right there, and if you donā€™t get the difference, thatā€™s fine, but it speaks to your level of understanding to how one actually goes about conducting scientific inquiry.

        And if you want to talk about incurious:

        You might as well say that the longer you stare at a printed painting, the harder it is to deny that printers make art. LLMā€™s do not ā€œunderstandā€ their outputs or their inputs. If we feed them nonsense, they output nonsense. Thereā€™s no underlying semantics whatsoever. LLMā€™s are a mathematical model.

        Specifically ā€œThereā€™s no underlying semantics whatsoeverā€ is the key lynch pin that UG demands that LLMā€™s demonstrate are not strictly necessary. Its exactly why Chomskys house of cards crumbles with the the counter-factual to UG/ Innate acquisition that LLMā€™s offer. I had a chance to ask him this question directly about 6 months prior to that op-ed being published. And he gave a response thatā€™s about as incurious about why LLM, and basically, big complex networks in general, are able to learn as youā€™ve offered here. His was response was basically the same regurgitation on UG and innate acquisition that he offers in the op-ed. And the key point is that yes, LLMā€™s are just a big bucket of linear algebra; but they represent an actually testable instrument for learning how a language might be learned. This is the most striking part of Chomskys response and I found it particularly galling.

        And it is interesting that yes, if you feed LLMā€™s transformers (Iā€™m going to start using the right term here: transformers) unstructured garbage, you get unstructured garbage out. However, if there is something there to learn, they seem to be at least some what effective at finding it. But that occurs in non-language based systems as well, including image transformers, transformers being used to predict series data like temperature or stock prices, even even DNA and RNA sequences. Weā€™re probably going to be having transformers capable of translating animal vocalizations like whale and dolphin songs. If you have structured series data, it seems like transformers are effective at learning patterns and generating coherent responses.

        Hereā€™s the thing. Chomsky UG represented a monolith in the world of language, language acquisition and learning, and frankly, was an actual barrier to progress in the entire domain, because we now have a counter factual where learning occurs and neither UG or innate acquisition are necessary or at all relevant. Its a complete collapse of the ideas, but its about as close as weā€™ll get because at least in one case of language acquisition, they are completely irrelevant.

        And honestly, if you canā€™t handle criticism of ideas in the sciences, you donā€™t belong in the domain. Breaking other peoples ideas is fundamental the process, and its problematic when people assume you need some alternative in place to break someone elses work.

          the key lynch pin that UG demands that LLMā€™s demonstrate are not strictly necessary

          You know what, Iā€™m going to be patient. Letā€™s syllogize your argument so everyone can get on the same page, shall we.

          1. LLMā€™s have various properties.
          2. ???
          3. Therefore, the UG hypothesis is wrong.

          This argument is not valid, because itā€™s missing at least one premise. Once you come up with a valid argument, we can debate its premises. Until then, I canā€™t actually respond, because you havenā€™t said anything substantive.

          The mainstream opinion in linguistics is that LLMā€™s are mostly irrelevant. If you believe otherwise ā€” for instance, that LLMā€™s can offer insight into some abstract UG hypothesis about developmental neurobiology ā€” explain why, and maybe publish your theory for peer review.

            You donā€™t need to put project a false argument onto what I was saying.

            Chomskyā€™s basic arguments:

            1: UG requires understanding the semantic roles of words and phrases to map syntactic structures onto semantic structures.

            2: UG posits certain principles of grammar are universal, and that syntactic and semantic representation is required as meaning changes with structure. The result is semantic universals - basic meanings that appear across all languages.

            3: Semantic bootstrapping is then invoked to explain where children using their understanding of semantic categorizes to learning syntactic structures of language.

            LLMā€™s torpedo all of this as totally unnecessary as fundamental to language acquisition, because they offer at least one example where none of the above need to be invoked. LLMā€™s have no innate understanding of language; its just pattern recognition and association. In UG semantics is intrinsically linked to syntactic structure. In this way, semantics are learned indirectly through exposure, rather than through an innate framework. LLMā€™s show that a UG and all of its complexity is totally unnecessary in at least one case of demonstrated language acquisition. Thatā€™s huge. Its beyond huge. It gives us a testable, falsifiable path forwards that UG didnā€™t.

            The mainstream opinion in linguistics is that LLMā€™s are mostly irrelevant.

            Largely, because Chomsky. To invoke Planckā€™s principle: Science advances one funeral at a time. Linguistics will finally be able to evolve past the rut its been in, and we now have real technical tools to do the kind of testable, reproducible, quantitative analysis at scale. Weā€™re going to see more change in what we understand about language over the next five years than weā€™ve learned in the previous fifty. We didnā€™t have anything other than baby humans prior to now to study the properties of language acquisition. Language acquisition in humans is now a subset of the domain because we can actually talk about and study language acquisition outside of the context of humans. In a few more years, linguistics wonā€™t look at-all like it did 4 years ago. If departments donā€™t adapt to this new paradigm, theyā€™ll become like all those now laughable geography departments that didnā€™t adapt to the satellite revolution of the 1970s. Funny little backwaters of outdated modes of thinking the world has passed by. LLMā€™s for the study of language acquisition is like the invention of the microscope, and Chomsky completely missed the boat because it wasnā€™t his boat.

              Your conclusion (which I assume is implied, since you didnā€™t bother to write it anywhere) might be something like,

              • Mathematical models built on enormous data sets do a good job of simulating human conversations (LLMs pass the Turing test)ā€¦ THEREFORE, homo sapiens lack an innate capacity for language (i.e., the UG Hypothesis is fundamentally mistaken).

              My issue is that I just donā€™t see how to draw this conclusion from your premises. If you were to reformulate your premises into a valid argument structure, we can discuss them and find some common ground.

                  Harsh words for someone who canā€™t even state a valid argument. I mean do you expect me to guess how your conclusion comes from your unrelated premises?

                  1. Roses are red.
                  2. Violets are blue.
                  3. An LLM passed the Turing test.
                  4. Therefore, humans lack an innate language capacity.
