The core difference is in the amount of intentional decisions being made by the artist. A prompt, no matter how specific, still delegates a lot of work to what is essentially chance. Something like Blender does make it easier to do certain things, but you still have to actively choose to do them. This is why AI-slop, no matter how detailed, will always feel off. It lacks the deliberateness of a human artist who knows exactly what they're doing and why at every level.
