All it can do is fill in the blanks with other people's work, and even that is something it does by rote. So you're not editing your own thoughts, which are formed by other fiction but also nonfiction and your own experiences and your thoughts on how to connect it all, just a lot of word vomit.

And you can't really edit that into something good, because the AI doesn't really understand what you're trying to do. If you want a heist, the AI doesn't understand what you like about heists or how this one fits into the larger genre, it just repeats the whole plot of "Ocean's 11” or whatever.
