I have to laugh about the AI vs. no AI debate. Mainly because I see this in other forms of industry. I'm a woodworker; if you look there, you will have people saying that if you use hand tools only, it's handmade, but the second you use a power tool, it's not. Then let's take it a step further. If you use power tools, it's handmade, but if you use a CNC machine, it's not.
AI is here to stay; if you dig your toes in, you're going to be left behind.
I agree with a couple of previous posts; as a reader, if the story is enjoyable, I personally don't care if you wrote it with AI or with pen and paper. And personally, I don't want to know what tools you used. At the end of the day, after I read a few chapters, if it's dry, lifeless, or boring, I will move onto another story. If someone wants to use AI and not put thought into their writing, they won't last long. Call it natural selection.
This is my personal opinion. And I'm sure it's not a popular one.
