No, you have a translation.
>Even if, like the Odyssey, there are hundreds of wildly varying translations?
Precisely why translations are not considered equivalent to the original text.
>What about an abridged copy? What about the Sparknotes version?
An abridged copy is not a copy of the unabridged version.
>If you have a copy of Pride And Prejudice And Zombies, do you have a copy of Pride And Prejudice?
No.
I'm honestly surprised these were the questions you chose to ask, when you could have asked what if you have 90% of the pages, or what if most of the pages are missing pieces because the book was shot with a shotgun, or what if the book was scanned and OCRed and all the "rn"s were replaced with "m"s and all the lower case Ls with ones. Hell, is a scan of the book close enough to having the book, or is it far enough that one can no longer be said to have the book anymore?
If I have a translation of a book, I think I have more of that book than if I had nothing at all. It's fuzzy.
You seem to be arguing that a translation, etc is not literally having the book, which is something that has always been my stance as well.
We just have different opinions about what it means to have a book. I think that having a copy of "Pride and Prejudice and Zombies" is more like having a copy of "Pride and Prejudice", than having no book at all is like having a copy of that book. You disagree and that's fine.
The reverse is not true. Just because someone asks a rhetorical question, does not mean they are using the Socratic method.
There's no technical reason why an LLM couldn't reproduce verbatim some of the training material. It's sort of a lossy statistical compression engine. Enough of the info will survive to the output in the original form. With the amount of data and the commercial nature it's hard to argue fair-use. But nobody tested this in court. I'm not even sure the US wants to ever test this. Why even attempt something that has a non-0 chance to sabotage your most promising industry/bubble in ages?
