I'm not sure you've understood my comment. Andy Warhol took other people's work and carefully changed it to make it his own unique piece. He might be accused of appropriation or theft of the original work, but the final piece looked like it did because he carefully crafted it that way. Some photographers (thinking Crewdson for example) use a large crew to create photographs, reputedly sometimes not even pressing the shutter himself, yet the work is plainly his because he guides it.
But, if I take one of my pictures and using the AI tools in a piece of software, allow the program to replace the sky with a stock one from the library provided in an unguided manner, I would suggest the image has lost integrity and there has been a philosophical loss of ownership of the image. Worse, if such images are used in competition we end up with the minner being the person with the best AI implimentation rather than the person who actually took the best picture. There are already often strict guidelines about compositing in some competitions, and I expect them to become more stringent. Last year I entered a picture in the TP DPOTY where I had composited the image to add rain falling, but I added it carefully, blending and angling the additional image, and also declared what I'd done at the time of entering - this was important for personal integrity, and also so that others could object if they felt it was unfair.
Copying painters were known to be copying - the actual making of the image was all their own work, but the creativity and strict ownership of the piece belonged to someone else. However those who just incorporate aspects of others work into their own, just like Warhol, would own the final image because it was their creativity and vision that produced the final work. Obviously that would be open to abuse, and could also result in tawdry, shameful work being presented as belonging to one artist when they had simply ripped off another artist badly in order to attempt to demonstrate creativity of their own - they might own the 'new' work, but it would still be a pile of foetid dingos kidneys.
And so, back to AI 'enhancement'.
Nice for phone snaps, but we need to be careful about representing an image about which we've made relatively few choices that influence the final look of the work, as if it were our own. In another thread I think it was
@gman who demonstrated the 'incredible' image enhacement ability of his Samsung phone, when as he kindly demonstrated what was really happening was the AI was guessing what was in the picture and replacing the photo with other content. This showed up when the leaves of one kind of plant were replaced by the leaves of something quite different. There was no enhancement, but only replacement.
