That's certainly a better heuristic, but then you quickly run into the problem of when the joke is objectively funny but politically incorrect, so people stop themselves from laughing so they don't get in trouble.
IMO, A.I., at least how it exists now, doesn't know what "funny" means or feels like, so it can't be funny itself.
If a real person said that, they'd just get an eye roll, but you know, since it's A.I., it gets a huge pass.
