If someone generates a ten thousand word slop essay with AI, do I have a moral obligation to critique its reasoning step by step instead of merely pointing out its origin?

If I do, it just so happens I have a ten thousand word rebuttal for you…

If someone generates a massive essay with AI, you don't have a moral obligation to do anything.

If you want to argue that the reasoning in the essay is incorrect, I do expect you to refute the reasoning instead of merely attacking the source.
