I've seen Grammarly commercials. What if I write some paragraphs, and then drag a big Grammarly slider across it, and it's no longer my words, but my ideas are still there, just buffed and touched up professionally? What's "AI generation" anyway? I wrote a limerick for a friend last week. Well, I had the idea for it and it was jangling inside my head, but I didn't feel like fleshing it out, so I had the AI write it. I was accused of "cheating". But I'm capable of writing this limerick; I just wanted to see if a computer could put a ribbon on it. And it worked fine. I claim authorship (and copyright) nonetheless.
