Those claiming AI training on copyrighted works is "theft" misunderstand key aspects of copyright law and AI technology. Copyright protects specific expressions of ideas, not the ideas themselves. When AI systems ingest copyrighted works, they're extracting general patterns and concepts - the "Bob Dylan-ness" or "Hemingway-ness" - not copying specific text or images.
This process is akin to how humans learn by reading widely and absorbing styles and techniques, rather than memorizing and reproducing exact passages. The AI discards the original text, keeping only abstract representations in "vector space". When generating new content, the AI isn't recreating copyrighted works, but producing new expressions inspired by the concepts it's learned.
This is fundamentally different from copying a book or song. It's more like the long-standing artistic tradition of being influenced by others' work. The law has always recognized that ideas themselves can't be owned - only particular expressions of them.
Moreover, there's precedent for this kind of use being considered "transformative" and thus fair use. The Google Books project, which scanned millions of books to create a searchable index, was ruled legal despite protests from authors and publishers. AI training is arguably even more transformative.
While it's understandable that creators feel uneasy about this new technology, labeling it "theft" is both legally and technically inaccurate. We may need new ways to support and compensate creators in the AI age, but that doesn't make the current use of copyrighted works for AI training illegal or unethical.
For those interested, this argument is nicely laid out by Damien Riehl in FLOSS Weekly episode 744. https://twit.tv/shows/floss-weekly/episodes/744
Your first point is misguided and incorrect. If you've ever learned something by 'cramming', a.k.a. just repeating ingesting material until you remember it completely. You don't need the book in front of you anymore to write the material down verbatim in a test. You still discarded your training material despite you knowing the exact contents. If this was all the AI could do it would indeed be an infringement machine. But you said it yourself, you need to trick the AI to do this. It's not made to do this, but certain sentences are indeed almost certain to show up with the right conditioning. Which is indeed something anyone using an AI should be aware of, and avoid that kind of conditioning. (Which in practice often just means, don't ask the AI to make something infringing)
I think you're anthropomorphising the tech tbh. It's not a person or an animal, it's a machine and cramming doesn't work in the idea of neural networks. They're a mathematical calculation over a vast multidimensional matrix, effectively solving a polynomial of an unimaginable order. So "cramming" as you put it doesn't work because by definition an LLM cannot forget information because once it's applied the calculations, it is in there forever. That information is supposed to be blended together. Overfitting is the closest thing to what you're describing, which would be inputting similar information (training data) and performing the similar calculations throughout the network, and it would therefore exhibit poor performance should it be asked do anything different to the training.
What I'm arguing over here is language rather than a system so let's do that and note the flaws. If we're being intellectually honest we can agree that a flaw like reproducing large portions of a work doesn't represent true learning and shows a reliance on the training data, i.e. it cant learn unless it has seen similar data before and certain inputs provide a chance it just parrots back the training data.
In the example (repeat book over and over), it has statistically inferred that those are all the correct words to repeat in that order based on the prompt. This isn't akin to anything human, people can't repeat pages of text verbatim like this and no toddler can be tricked into repeating a random page from a random book as you say. The data is there, it's encoded and referenced when the probability is high enough. As another commenter said, language itself is a powerful tool of rules and stipulations that provide guidelines for the machine, but it isn't crafting its own sentences, it's using everyone else's.
Also, calling it "tricking the AI" isn't really intellectually honest either, as in "it was tricked into exposing it still has the data encoded". We can state it isn't preferred or intended behaviour (an exploit of the system) but the system, under certain conditions, exhibits reuse of the training data and the ability to replicate it almost exactly (plagiarism). Therefore it is factually wrong to state that it doesn't keep the training data in a usable format - which was my original point. This isn't "cramming", this is encoding and reusing data that was not created by the machine or the programmer, this is other people's work that it is reproducing as it's own. It does this constantly, from reusing StackOverflow code and comments to copying tutorials on how to do things. I was showing a case where it won't even modify the wording, but it reproduces articles and programs in their structure and their format. This isn't originality, creativity or anything that it is marketed as. It is storing, encoding and copying information to reproduce in a slightly different format.
EDITS: Sorry for all the edits. I mildly changed what I said and added some extra points so it was a little more intelligible and didn't make the reader go "WTF is this guy on about". Not doing well in the written department today so this was largely gobbledegook before but hopefully it is a little clearer what I am saying.
I never anthropomorphized the technology, unfortunately due to how language works it's easy to misinterpret it as such. I was indeed trying to explain overfitting. You are forgetting the fact that current AI technology (artificial neural networks) are based on biological neural networks. There is a range of quirks that it exhibits that biological neural networks do as well. But it is not human, nor anything close. But that does not mean that there are no similarities that can be rightfully pointed out.
Overfitting isn't just what you describe though. It also occurs if the prompt guides the AI towards a very specific part of it's training data. To the point where the calculations it will perform are extremely certain about what words come next. Overfitting here isn't caused by an abundance of data, but rather a lack of it. The training data isn't being produced from within the model, but as a statistical inevitability of the mathematical version of your prompt. Which is why it's tricking the AI, because an AI doesn't understand copyright - it just performs the calculations. But you do. And so using that as an example is like saying "Ha, stupid gun. I pulled the trigger and you shot this man in front of me, don't you know murder is illegal buddy?"
Nobody should be expecting a machine to use itself ethically. Ethics is a human thing.
People that use AI have an ethical obligation to avoid overfitting. People that produce AI also have an ethical obligation to reduce overfitting. But a prompt quite literally has infinite combinations (within the token limits) to consider, so overfitting will happen in fringe situations. That's not because that data is actually present in the model, but because the combination of the prompt with the model pushes the calculation towards a very specific prediction which can heavily resemble or be verbatim the original text. (Note: I do really dislike companies that try to hide the existence of overfitting to users though, and you can rightfully criticize them for claiming it doesn't exist)
This is incorrect. A toddler can and will verbatim repeat nursery rhymes that it hears. It's literally one of their defining features, to the dismay of parents and grandparents around the world. I can also whistle pretty much my entire music collection exactly as it was produced because I've listened to each song hundreds if not thousands of times. And I'm quite certain you too have a situation like that. An AI's mind does not decay or degrade (Nor does it change for the better like humans) and the data encoded in it is far greater, so it will present more of these situations in it's fringes.
How do you think toddlers learn to make their first own sentences? It's why parents spend so much time saying "Papa" or "Mama" to their toddler. Exactly because they want them to copy them verbatim. Eventually the corpus of their knowledge grows big enough to the point where they start to experiment and eventually develop their own style of talking. But it's still heavily based on the information they take it. It's why we have dialects and languages. Take a look at what happens when children don't learn from others: https://en.wikipedia.org/wiki/Feral_child So yes, the AI is using it's training data, nobody's arguing it doesn't. But it's trivial to see how it's crafting it's own sentences from that data for the vast majority of situations. It's also why you can ask it to talk like a pirate, and then it will suddenly know how to mix in the essence of talking like a pirate into it's responses. Or how it can remember names and mix those into sentences.
If your arguments is that it can produce something that happens to align with it's training data with the right prompt, well yeah that's not incorrect. But it is so heavily misguided and borders bad faith to suggest that this tiny minority of cases where overfitting occurs is indicative of the rest of it. LLMs are a prediction machines, so if you know how to guide it towards what you want it to predict, and that is in the training data, it's going to predict that most likely. Under normal circumstances where the prompt you give it is neutral and unique, you will basically never encounter overfitting. You really have to try for most AI models.
But then again, you might be arguing this based on a specific AI model that is very prone to overfitting, while I am arguing this out of the technology as a whole.
It is originality, as these AI can easily produce material never seen before in the vast, vast majority of situations. Which is also what we often refer to as creativity, because it has to be able to mix information and still retain legibility. Humans also constantly reuse phrases, ideas, visions, ideals of other people. It is intellectually dishonest to not look at these similarities in human psychology and then treat AI as having to be perfect all the time, never once saying the same thing as someone else. To convey certain information, there are only finite ways to do so within the English language.
