I agree. I think that most of these won't be true in smart usage. For instance (not an encouragement), Ai can be program to have occasional spelling errors that is typical of humans. I didn't see that reflected in the piece. Maybe I missed it, since I'm not Ai.
That bein said, Ai's best usage right now is for the writer to complete the script his/herself and have it modify for tone and grammar. Can even have a conversation about why things are a mess and where they can be improved if that is the case. But I'm sure you probably have or will discuss that.
