Humans are punished for plagiarism all the time. Myriad examples exist of students being disenrolled from college, professionals being fired, and personal reputations tarnished forever.
When a LLM is trained on copyright works and regurgitates these works verbatim without consent or compensation, and then sells the result for profit, there is currently no negative impact for the company selling the LLM service.
I can be in a room looking at something with my eyeballs and listening with my ears perfectly legally... But it would not be legal if I replaced myself with a humanoid mannequin with a video camera for a head.
You can even write down what you are looking at and listening to, although in some cases, dissemination of, e.g. verbatim copies in your writing could be considered copying.
But it is automatically copying if you use a copier.
Exactly. We assess plagiarism by checking the output (the book), not the input (how many book I’ve read before). It’s not an issue to train LLM on copyrighted resources if their output is randomized enough.
