You could phrase this, 'when is it "okay" to plagiarize writing,' because that's what using generative AI is. It's plagiarism. All LLMs are mass theft machines.

Maybe when "writing augmentation" isn't based on LLM technology we can have a more nuanced conversation about this, but for now it's 100% unethical, and that's before we even get into the whole energy consumption issue.

Whether it is "real" or not is a distraction.
