And the exact same thing can be said of more than a few human beings too.
Humans are special.
But no one is suggesting that people be forbidden to read and learn the plots, locations, background details, and characters of those books.
Agreed. The contents of your mind are beyond the reach of copyright.
But the contents of your computer memory and hard drives are not.
Memorize it all you want, but copies on your computer are legally different.
Nor is is it being suggested to forbid people from showing off or passing on their knowledge.
Well, yes, people ARE forbidden from doing exactly that.
For example, if you want to recite lord of the rings to a paying audience? you need license for that. Translate it to Klingon and distribute copies?... you need a license for that too.
Sure you can show off to friends in a bar or around the kitchen table all you like privately. That's all fair use. But try to commercialize it and distribute it, broadcast it, or perform it? Yes, people also need a license for that.
AI companies by and large are for profit enterprises copying data that doesn't belong to them and exploiting it for commercial gain by training LLMs on it. LLMs aren't people. It takes input, it runs an algorithm, it generates output. For it to have a model of LotR in there, either the model is getting passed in the prompt the user gave it (it's not) or its getting in there via the training on the copy of LotR and everything else that was fed in (yep this one). So copies were made to train, and some sort of derivative copies are persisted inside the model data too... which then are commercially exploited.
And even if it did work exactly same way as a human brain worked it still wouldn't matter, because its still a computer, and memory and storage, and those things are all treated by copyright law differently from a human mind.
