The Uncanny Valley
AI struggles with the precise topology of the human body. While it can render a convincing "texture" of a person, the underlying structure often mistakes probability for biology.
The Hand Problem
Hands are the most notorious AI failure. Why? Because in training data, hands are rarely seen flat and open. They are holding cups, waving, clenching fists, or partially hidden.
- Polydactyly: The "Six Finger" glitch. AI doesn't know humans have a limit of 5.
- Knuckle Erasure: Fingers often look like smooth sausages without joints.
- Palm Merging: Fingers often sprout from the wrist or merge into the palm.
Ocular Asymmetry
The "Windows to the Soul" are often where the illusion breaks.
Pupil Shape
Real pupils are perfect circles. AI pupils often have jagged edges aka "amoeba shape."
Catchlights
The reflection in the eye MUST match the light source. If one eye has a window reflection and the other has a studio light, it's fake.
