Dunno what you want me to say. Define the vague concept of "good writing"?

The linked study finds that ChatGPT 3.5 and Bard suck at writing comedy. You claim in so many words that this should be obvious (along with a really dubious claim that machines can't tickle people for some reason). I'm also not surprised that these models are terrible at writing comedy, because even at best of times I find their output bland, trite and crudely stripped of anything potentially divisive.

However, lots of people seem to think that LLMs are good at writing related tasks, so I don't think it's inherently obvious that these tools suck at writing comedy in particular.

All these words make this reply much less fun to write.
