Why is it different other than, "just cause?" No one seems to have actual reasoning to back it up while it feels very similar the other way around, is human brains and neural nets (notwithstanding that they're both called neurons) seem to learn similarly and can act on similar classes of problems like language and mathematics.
There are several distinct differences, I think the most pertinent one is that you can create seperate instances of the LLM that ingested that media without reingesting the media (i.e. you can copy the LLM but you can't copy a human). Copright law is screwed up for multiple reasons but it makes sense to treat LLM as different than a human consuming the media, especially if the LLM is created for profit (e.g. movie owner selling tickets to a dvd he bought in the store vs a home viewing is treated differently).
What's the difference between humans and LLMs? The difference is that the creators of laws are humans, and the purpose of laws is for humans. Authors write books with the expectation that they will be read by humans, and copyright law was written with unstated assumptions, like the fact that books have an effect on a person's mind after reading it.
IMO the spirit of the law would prohibit LLMs from training, and the letter of the law leaves room for that only because nobody thought to write down "books are for people to read".
Laws are not only for humans, there are laws for bots as well, like anti spam, but that's besides the point because in reality behind LLMs there are humans and so humans still control them, therefore laws target them too, and now it looks like humans using LLMs to train via ingestion of books is deemed fair use.
I agree that laws don't only apply to humans, but they are only for humans. The legal system is for our benefit.
> therefore laws target them too, and now it looks like humans using LLMs to train via ingestion of books is deemed fair use
Which is orthogonal to my point.
are you asking what the diff is between a human and an LLM?
LLMs are just tools wielded by humans. There's always a human behind whatever is done.
I asked why, not what.
