Well, we could all have our own personal army of Korean animators and programmers. That would have the same effect as using AI in that the author can write the script and have someone or something else do that kind of thing that they may not enjoy or have the skill to do.
I've seen this same argument to say that because it used ripped game music files from various commercial JPRGs that Exit Fate is bad in some way. I would say that to date that is my favorite one so far, and if they had to go through all the work of making their own soundtrack there's a good chance it would have never been released.
