Art isn't just the screenplay, or a prompt; it's the clash between reality and the intent (whether a location or practical set constraints), the individual skill of everyone involved, costume and prop department. And it may change during production. And effort. If it's easy, it's easily reproducible and not worth that much. And novelty, that's something current models aren't capable of. That's why Jarimoquai's Virtual Insanity video became popular. That's why practical effects are more impressive than CGI, even if they're jankier and hide behind clever camerawork.
