If I was feeling unfair I would say there is no difference! However, if a friend drew me an eye on A3 paper would I frame it? Probably yes...
Others have said this better, but art is an qualitative/emotional thing, not a simply measurable quantity of an object. We tend to use the effort put in as a proxy measure for quality, but when photocopiers and 3D printers and - yes - genAI get involved, that becomes harder or impossible.
Beating Guitar Hero is emotional, but not artistic. Photorealistic drawings could be emotional, and may or may not be artistic. Putting a text prompt into a generative model to make a (frankly terrible) music video for $100 is ... something else.
Anything can be artistic, but some things are very hard to make artistic.
Beating Guitar Hero could artistic. I don't even know how, but I'm sure some artist could beat Guitar Hero in a way that was somehow artistic.
This terrible $100 music video which I'm not even going to watch, is surely not art. Also I'm totally sure some person is going to spend $100 with an AI and make art. It's very hard, but they day will come. The slop-to-art ratio will be astronomical.
