If it were possible to tell, at a glance, whether something was or was not AI, it would not be causing nearly the social harm that it does.
It seems like you’re shifting away from the point of discussion, which was whether AI output can be art, and more towards the general dangers of the technology itself, which is a whole other discussion.
My opposition is to demon tech produced by vampires.
It also seems like this discussion is taking a toll on you. If you are interested in continuing it, there’s no harm in taking a step back and coming back later.
there is hardly confusion about whether something is or is not a photograph.
This proposition is refuted by hyperrealistic paintings such as La hora del té by Magda Torres Gurza. You can see that this is not a photography if you pay attention to the reflections. But certainly not at “first glance”.
