AI is very good at writing things that don't need to be written. (That's why it's great for homework -- the purpose of the assignment is to write it, not to tell the teacher something they already know.) For any process where AI is used in writing text, that tells me that we should consider changing, or eliminating, the process.
The one that really strikes me is legal briefs. If lawyers think that AI can write briefs, maybe we don't need the briefs at all. Perhaps there is some more concise form that standard legal arguments should be written in?
But what if they find willing stupid audiences?
After all people read Buzzfeed and other such crap, or all the older pre-AI human made self-help, outrage, gossip slop.
