I think the fact that generative models, especially modern LLMs with reasoning and tool calling (agents), can clearly do useful things, plus the fact that these models are trained on basically the sum of all digitized human creative work, is possibly the most persuasive argument we have so far for abolishing copyright. Right now, only the powerful can ignore copyright with impunity. What they have now should be available to all of us, and not just indirectly through the models they let us use.
