Earlier quoted context omitted.
Either you completely missed my point, or you genuinely believe that my first executable is legal. Which one is it?
I do not buy the premisses. Your example states that it can provide the full text of any book. An LLM cannot do that. They can produce something in the same style and setting. When an actual human author mimics other writers styles, it is not illegal, why exactly should it be illegal for an author to use an LLM to do it?
There is a fundamental difference of scale. Say I write a blog post about some technical thing I know. You read it, learn from it (and other sources), and then you write your own blog post with your understanding. You may link to my post (if you believe it is heavily inspired from there), or not. But reading my post, understanding the material to the point where you can write about it took time. If you are so fast that you can produce more posts than I do, and your posts are the same quality, then suddenly you become a better blogger than me.
An LLM can automate that. With an LLM, you as a blogger don't have to learn from my post, you can just have it generate the post (you don't even need to read it). In that case, you have put absolutely zero effort learning about the topic, you just had some algorithm copy-paste-and-modify my post. Don't you think that if you publish a blog post that you haven't even read yourself, probably it comes from material written by somebody else at some point?
In any case it is very different. Once a human does it, the other time a machine does it. I don't understand why engineers think we can just transfer concepts between both. You as a human have rights (maybe you can vote), but your LLM cannot. Why couldn't an LLM vote if humans vote? Precisely because it is different, and it creates new problems.
The fact that LLMs can automatically (and at scale) launder copyrighted material is a new problem. Therefore we need to think about that, and to think about whether or not this should be legal.
The day people stop reading my blog and instead use ChatGPT (which is trained using, among the ton of other copyrighted material, my blog), and as a result nobody reads my blog directly anymore, I can assure you that I will stop writing. If 99% of books are written by ChatGPT instead of actual authors, but based on books from actual authors, in such a way that the readers don't really make a difference and therefore go with ChatGPT (because it's cheaper), what do you think writers will do? If they can't live from writing books (because ChatGPT does not buy their books, and people now pay ChatGPT instead of buying the books), then they will just stop writing.
It is a risk that needs to be considered. And it's certainly not an engineering question.
