Don't understand this discussion at all. There's no need to flip your position due to AI. Any produced work may or may not infringe copyright. If you produce a work that lifts say, characters or expressions straight out of a story you're likely violating copyright. If you used AI tools to produce that same work it still does. It's irrelevant how you technically produced the work, by pen, typewriter or chatbot api.
Asking if training a model violates copyright is unintelligible because 100 GB of weights don't resemble any work unless you produce and publish inferences from it.
