A bunch of turned-off Dell Windows 95s aren't sitting in the corner of a storage closet spontaneously forming art. (If anything, that sounds like an "artist art" exhibit).

Someone picks up a paintbrush, balances an easel, puts hair to palette to canvas.

Someone picks up a digipen, powers their tablet, puts silicone to glass.

Someone picks up a 4090, accumulates loras and prompts, puts photoshop and inpaint.

When does "art" cease to become "art"? When does "artist" cease to become "artist". In all three cases, the "artist" has viewed thousands of works of art, studied their dimensions and what makes art popular/good or not, and applied those learnings to the result. They copy shortcuts and "secret techniques". They trace, sketch, record images to their minds for reference later.

If you're against AI art, you should also be against the standard idea of painting on canvas. Can you imagine not making your own paints? Not making your own paper? How is it even art if such processes are automated for you?
