Let's take the Echoes of Olympus game as an example.
The author states they used AI because they aren't a native English speaker.
As someone who's also not a native English speaker, and also an author, I think they're doing themselves a disservice by taking the easy way out. Why? They're never going to develop their English writing skills if they use AI to translate for them. They're not going to develop an author's voice, a unique writing style, or even just the understanding of the language needed to edit/improve their text.
Of course, these are not the things that everyone worries about. The author said they just want to get the story out. Fair enough. But you're not going to develop any writing (and related) skills if AI is doing it for you.
That's my perspective anyway.
On this kind of thing, I'd like to issue my own input.
My pen comrade is using AI to develop some drafts for her characters very quickly and then she updates the drafts according to her needs. Given that she doesn't really have free time, this little writing does her good. Because she'd love to be a full time writer one day.
Her actual writing style was cosmic horror levels of cynicism, so the AI helped her develop more voice styles in more ways!
It's fine, she's fine, I love her for it. She's honest, and finally found a tool that helped her get some lines to paper when she's burned out.
Now Halls of Sorcery, that abomination made me

I written story backed by the same company that diabolically tried to sneak in its first AI book, and then pretending they

, is another primordial level of corporate arrogance.
A girl unable to think of lines due to exhaustion is nowhere near as bad as what CoG dared try to do sneakily.
