You can use AI as part of your editing process. But it needs to be a process, back and forth with human input, and human editing at the end. What people primarily complain about it pure AI text. It has sentences a paragraph long using every punctuation mark invented by man. If you look at book you'll notice the same style of punctuation used but it'll be at 10% of the rate. You won't see n/m-dashes, commas, colons, semi-colons, and parentheses all used in a single sentence.
