I think trying to place such limitations on what gets defined as art shows a rather fundamental weakness in your position instead of strengthening it.
I think this is rather ironic, given what you're arguing actually diludes the concept art into meaninglessness. Which, as it is, tracks.
As Ive mentioned before, I've had this conversation more than once. You don't sound any different from people who have a very cynical, contemptous attitude towards artists.
For me, that's not evidence that such wasn't art, it's evidence of that art not meeting the expectations of the person who hired you.
No, its evidence that it wasn't art, because cropping a stock image is not artistic.
Again, we tread the same waters of cynicism and contempt for what artists actually do.
Being 'art' is not something dependent on the amount of effort put into the 'art'. Nor of the quality in the end.
Then you're not aware of what actually goes into artistic works.
Another fun anecdote from my life; as a kid I had a pretty substantive magician phase, and being the the likely ADD riddled perfectionist I was, I got pretty good at it too despite being between 8-10 years old when I started.
Over time, I eventually gravitated towards card flourishing and eventually the whole "XCM" phenomenon at the time, and I again got pretty good, and to this day I still retain the muscle memory to perform more or less at the same level.
The thing about card flourishing, and really sleight of hand work in general, is that it takes a tremendous amount of practice just to be able to do certain moves for the first time, and it takes a considerable amount more time and skill to be able to do them in a way thats not only aesthetically pleasing as part of a routine, but is also consistently perfect.
Pretty much anyone can make a cruddy looking card fan with a deck. Not everyone can make one thats sufficiently large, displays all the pips, is evenly spaced, and can be thrown from one hand to another without the cards spilling everywhere.
And yet, some people, who carry that same cynical, contemptous streak, liked to say that what I could do with a deck of cards wasn't impressive; that I was merely flipping cards around.
Naturally, if I handed them the deck not only were they incapable of any of the things I could do, but they'd often end up ruining the deck to some degree just because they don't know how not to grip a deck of cards like you're suffocating it.
Thats a clear example of why artistry can't be so reduced to meaninglessness, because theres more to it than you're giving it credit for by trying to assert any random thing can just be called art.
The point is that no 'art' today is produced in a vaccum.
Which as explained is a non-sequitor to what was being talked about.
Ever seen a person that's been blind for his whole life paint? That's basically the equivalent of an Art AI without any training data.
Blind people have 4 remaining senses. Art isn't just a visual medium, and even a blind person can accomplish quite a lot without sight:
Esref Armagan didn't need to be born with sight to paint that, and definitely never needed to see another painting either.
If no human today does art that way, then why does it matter whether they theoretically could?
For one, some humans do. See Armagan.
And for two, as already said, that discussion is specifically about what sets apart AIs and Humans in regards to whether or not AIs are actually capable of creating art.
Examining whether or not a human can create art when no art exists is a thought exercise that demonstrates the clear dividing line between the AI and the Human.
A human does not need to see art to produce an example, and does not need to see art to improve upon their own works. AIs do, and thus, they are not producing art.
