Exactly right. Clutter (lack of substance that would contribute to the body of knowledge) is the target. Please note as well this line from the Moderation Team Guidelines:
Sharing of accurate information that contributes to general knowledge created through artificial intelligence, such as computer code, step-by-step instructions for procedures, and the like, is of course always permissible.
Using AI to assist a human writer with grammar and syntax is certainly not the target. Using AI to help a human writer translate from one language to another is certainly not the target. The target, again, is substance-free content that appears to have been generated by AI.
