An interesting paper from law professor Michael D. Murray that investigates the question of who owns artworks that are generated by computers and AIs:

“Artists and creatives who mint generative NFTs, collectors and investors who purchase and use them, and art law attorneys all should have a clear understanding of the copyright implications involved with different forms of generative art. This guide seeks to educate each of these audiences and bring clarification to the issues of copyrights in the world of generative art NFTs.”

He concludes that in many cases they are uncopyrightable – including lots that are the basis for lucrative NFT projects.
