I strongly feel that this is a terrible metric for comments on the internet.
First, the person you’re replying to has nothing to gain and a lot to lose by saying "yes".
Second, it invites silly corner case nitpicking. Their comment is written in reasonable plain English for other users reading plain English. It’s not a legal contract, and so leaves lots of loopholes. Sure, you could create a likely non-transformative LLM by training it on nothing but the text of Harry Potter with fitness measured by how accurately it exactly reproduces the complete text of Harry Potter, but that’s not what reasonable people are doing with LLMs.
In a legal context certain words have immense power. In the context of copyright 'transformative' is one such case. It's a very fine line between 'transformative' and 'derivative' and you don't get to preempt the judiciary about how they will see things.
Designing systems around what people should do, as opposed to what they actually do, has proven time and again not to work particularly well in practice. I'm sure you've seen countless examples of how people track paths through manicured grass fields. The landscaper will complain about how people should walk and they'll put up signs to no avail.
The fact is, we (including me, BTW) are frequently wrong about a lot of things, and when there's little riding on it, we can ignore that most of the time. With subjects like medicine and law, however, where a mistake can cost you your life or lots of money, we want to make sure people are getting the best advice possible. That's why we require licenses to practice medicine and law, and we have governing and ethics bodies to regulate how professionals operate their practices.
Correct, so people should (and do) go to the people who have these licenses, not random people on the internet. I don't even understand what your solution, or even problem, is. It seems like you're suggesting that everyone, whenever they speak on the internet about anything vaguely related to medicine, law, or hell, even regulated fields like engineering, should disclaim that they are not speaking in such a context. And I saw that that is a ludicrous task that is expected of one to do. So if you have any better solutions, let me know.
Because 'transformative' is a pretty dangerous word to use in this context.
