If after 33 comments in this thread and countless people trying to explain a part of it you don't get it that may be because you either don't want to get it or are unable to get it. Restating it one more time is not going to make a difference and I'm perfectly ok with you not 'getting it', so don't worry about it.
AI without real art as input is noise. It doesn't get any more concrete than that. Humans without any education at all and just mud and sticks for tools will spontaneously create art.
This is a difference between using a gradient in Photoshop, which is still a tool, and generative AI which will make "decisions" you as an author can't explain or connect with.
natural question: to you draw? Even a simple thing, even a doodle of a cat would count. A particular emoji drawn for a joke. Have you ever drew a line, and then smile to yourself "yes, that is what i want other people to see?"
People can draw poorly or make collages, and come up with pretty expressive art. Those who say "well I can't express myself with stick figures" coincidentally can't express anything without stickfigures too. They just never payed enough attention to the subject to express it.
Personal anecdote: when I ask people why X is in the art they send me, they answer happily. When I ask people with AI art that, they say "oh, you nitpicking". As if some details don't and shouldn't influence art expression. As if all details that weren't in a prompt, shouldn't express anything.
AI art is a concept muddled. It's a grave for intentionallity. It's not easy to decipher creators intent through a cacophony of other intents mixed in because almost none of art choices were made with the intent to convey.
