A painting can be distinguished from a photo from its physical dimensions and attributes like texture. If I take a photo of a painting, almost nobody is going to file a court case against me for putting it in a book or website or tv. We're collectively ok with that level of reproduction.

An AI work can currently be determined by looking for 'errors' that aren't likely to be drawn in by artists or found in reality. Inconsistent shadows, exact repetition of organic pattern details, extra limb bits, doesn't construct language fluently, etc. We're not necessarily ok with that level of reproduction though because it is slightly less obvious at first glance.

Just like photos are a lossy format for paintings, AI is a lossy reproduction tool. While it will definitely be harder to distinguish with time, we're sort of still left with the core problem. What fidelity reproduction is necessary for something to no longer be original? And what does the originality actually matter when people don't need to rely on producing it to eat?

Hell, people even bought NFT apes with cut and pasted Mr. Potato Head parts for thousands. People have photocopied photos of the Sistine Chapel in books for close to free. Maybe it's just cool that the imagery is resonating with people regardless of the medium.

Also, we should feed people without the expectation of financial return, thanks for coming to my tired tedx talk.

If AI gets to the point where it can truly replicate anything, even so it won't be the end of human creativity, so I expect humans will still be making new things and new forms of art.
