At the end of the day, the so-called AI generated art is a result of millions of artworks which were consumed by the AI model while training. I always like to draw parallels between AI copyrights and NFTs in the Web3 world. While minting NFT == having a digital copyright on the art piece, you pay a gas fees for doing so which gets distributed to the community as a reward to enabling it. I would love to see similar mechanisms in the AI world where the community get rewards for someone using Stable Diffusion (and not just Stability AI).
