Imagine this situation if a human replaced the AI.

Imagine a human who wants to write a book. They've read hundreds of other books already, and lots of other things besides books. Then they write a book. The final work probably contains an amalgamation of all the other things they've read--similar characters, themes, plot points, etc.--but it's a unique combination, so it's distinct from those other works. No copyright violation.

Now imagine that same human has only ever read one book. Over and over. They know only the one book. The human wants to write a new book. But they only have experience with the one they've read again and again. So the book they write is almost exactly the same as the one book they read. That's a copyright violation.

Training an AI model is not a crime, any more than reading a book is a crime. You're not making "copies" or profiting directly from that single work.
