Chess is objective, stories and style are subjective. Humans crave novelty, fresh voices, connection and layers of meaning. It's possible that the connection can be forged and it can get smart enough to bake layers of meaning in there, but AI will never be good at bringing novelty or a fresh voice just by its very nature.

LLMs are frozen in time and do not have experiences so there's nothing to relate to.

I'd pay extra for writing with some kind of "no AI used" certification, especially for art or information
