alt Hacker NewsWell, Duchamp's fountain is a great illustration that "art is fundamentally about communication." does not entail that a cultural/artistic artifact has to be created by the author at all. I as well can create a short story with help of an LLM and say - this is my vision and what I always wanted to say.
I have actually referenced Duchamp's Fountain before in similar conversations about AI art because I think it's a great example of what makes art art. The art itself isn't the toilet, it's the act of elevating a toilet to the status of art. If you don't know the context of the physical item, it loses all artistic merit because the item itself is not the art. The whole thing is more performance art than sculpture.
I'll freely admit that LLMs can be used in art in a similar way. You can certainly make LLM output the core of some performance art piece, but that doesn't make the LLM's output art itself or make it interesting on any level outside the context of its creation. Engaging with that short story as its own art would be like primarily judging the Fountain on the aesthetic qualities of the curves of the porcelain.
