By this same logic, AI will also become accepted as art in 50 years. And by the way, no one who's serious about AI "art" uses commercial generators, they use local AI with workflow managers like ComfyUI. They are not just typing into a box like Midjourney. Therefore these are the hackers who're showing the middle finger to Disney, they dislike copyright as much as anyone.
That's right, and a lot of stuff is being conflated and the "debate" is mostly on the level of soundbites and emotional vibes. Many have strong opinions who have never tried the models or seen someone skilled using them (easy to find YouTube streams), combining LoRAs, ControlNets, etc.
I generally find the specific debate around "whether it's art" super boring. People have squeezed all the juice out of "what even is art" decades before the banana taped to a wall. Duchamp's Fountain, Manzoni's Artist's Shit, John Cage's 4′33″, the Red Square by Malevich, Jackson Pollock etc.
I simply don't care if it's art. It's not an inherently prestigious label to me given this history.
