Because I'm actually curious if they mean "new" as in "a new knock-knock joke" (which imo is a quite small step especially if you are allowed to screen all attempts and only publish the ones that work) or as "a new kind of joke or way of telling a joke" (which is a giant step especially if it's told live without pre-screening by a human).

I'm all for dismissing LLMs and the AI-hype but I'm also interested in trying to understand what it means to be human and I think humour is a key aspect.
