AI will probably pass that test. But art is about experience and communicating more subtle things that we humans experience. AI will not be out in society being a person and gaining experience to train on. So if we're not writing it somewhere for it to regurgitate... It will always feel lacking in the subtlety of a real human writer. It depends on us creating content with context in order to mimic someone that can create those stories.
EDIT: As in, it can make really good derivative works. But it will always lag behind a human that has been in real life situations of the time and experienced being a human throughout them. It won't be able to hit the subtle notes that we crave in art.

It can absolutely do that, even today - you could update the weights after every interaction. The only reason why we don't do it is because it's insanely computationally expensive.
