I'm just referring to the fact that they said "But it does not understand anything here" even though the parent comment made no such claim. The parent was saying ChatGPT made a bullshit answer that even tricked OP into thinking there was understanding.

I think the disagreement is about the fact that it would be considered specifically impressive. It doesn't seem more impressive than everything else ChatGPT does when it repeats a boilerplate and tries to find parts of a joke using probabilistic weights, or tries to categorise the joke into either puns or something else.
