What AI art needs is more control over the process.
In music production, keys, knobs, sliders, touch pads, etc. give an interface for the human, enabling more expressive and tweakable experiences.
AI art needs more stuff to tweak than a text prompt.
A lot of non art people talk about how AI eliminates drudgery and allows us to "focus on being creative" As if they even know what that means.
They don't understand that the process is where the creativity happens. It's in all the small choices you make along the way.
