Absolutely inevitable if you condone using GAI to ‘assist’ in writing. The inevitable outcome is reporters just writing prompts and giving it a quick once over, then skipping the last step because they believe the companies selling generative AI and/or are under time pressure and it seems good enough.
They are word generators. That is their function, so if you use them words will be generated that are not yours and which are sometimes nonsense and made up.
The problem here was not plagiarism but generated falsehoods.
