My wife and I went for wall decoration. There’s an art gallery and a poster shop right next to each other. The price difference is a factor 100 for an average art piece.
In the poster shop you can choose between a bunch of classics, or you can upload your own AI-generated picture and have that printed as a poster.
Art was always expensive, and posters as an alternative to paintings existed way before AI. Same with copying all kinds of art.
The main difference seems to be that we can’t clearly pay royalties to anyone for AI artwork, because it’s not obvious exactly where it came from.
There was a YouTube channel dedicated to Warhammer lore narrated by an AI David Attenborough. It got taken down for infringing on his voice, but its replacement came up, starting out with a generic old man’s voice and over time gradually more Attenborough-like. When should the Attenborough estate start to get royalties? At 60% Attenborough? Or at 80% Attenborough?
In my original comment I was asking people to follow me into an imaginary future where there are less artists. Artists reveal something about the world that speaks to us, which they do through critically breaking down and reforming what they see. I can't remember who said it, but they said when art speaks to you, it's a momentary bridge between the artist's soul and yours.
I'll answer your question, but my question for you is: why were you buying wall decorations in the first place? To me, it sounds like you were searching for a product category, and not specifically for art.
Regarding your example, if the AI is capable of imitating David Attenborough by including his name in the prompt, then it was probably trained on his data. If he didn't consent, then I might argue that is ethically wrong and, in my view, theft. If the channel was not monetized and done without his consent, I might argue that is just an ethical failing. In using his voice, the channel betrays the fact that it has value, otherwise they would continue to use the random old man voice.
