AI can help you in this case as evidenced by the chat I shared. I do suggest you use it and not keep trying to save face by dodging the question.
I ask you again, what edge case does there exist for an LLM that an LLM can't perform but a human can?
Without dodging the question or asking me sheepishly to ask an LLM, can you unambiguously answer the question with a single edge case?
If you still can't answer me with a single edge case that a human can do but an LLM can't (in text and limited context) then it is clear you are trying to save face.
