AI-generated models are attractive for one simple reason: they remove human limits. A real person has a body that ages, fluctuates, gets tired, carries asymmetry, carries history. An AI model does not. It can be adjusted, perfected, smoothed, slimmed, reshaped, relit, and regenerated without resistance. There is no baseline reality pushing back. Advertising has always idealised people, but it used to start from something that existed in the world.
