Optical illusions expose fundamental issues in human perception, which we generally can't adapt to. This is similar. [edit, fwiw]: Also consider that humans can't perceive ultrasonic sound frequencies, or light outside a certain frequency range... We have eventually invented ways to perceive beyond our physical limitations, but no amount of individual adaptation can overcome these boundaries.
