I'm not sure I think learning how to make a robot use limited vision
from simulated artificial vision gets the answer of how to improve
artificial vision for people to process, but who knows, it might?  you
have to try many alternatives to find the best solutions to problems,
and may as well try them on machines for most of the repetitions.
