Because the toy in the video doesn't do what it claims to do. The YOLO library does, in fact track his face. The $5 servos controlled by the arduino on the left are not actually keeping up though, nor would they accurately align with the camera.

Finally, YOLO only works well at that range while it has a well lit face from one angle. It won't be able to do that tracking with shadows / objects moving in the background, etc.

YOLO is "AI", even though OpenCV motion detection with ByteTrack isn't and can do the same.

Not if it moves.
