I think it is definitely the other way around. An AI will generate the kind of simplistic stories I need for my current level of proficiency in my target language. An actual human will more often than not slip some complex grammar and vocabulary before I am ready for it. When you are at B2-C1 level, then you can appreciate the nuances of human generated stories, but for A1-A2, what difference would it make? The AI is better because it will make all the content I can consume, immediately and ready.
