This is why it would seem the biological approach to this will probably be
the most promising.  From what is known, everything needed for site to work
may be encoded in our geens, including the mechanisms for restoring the
brain's ability to effectivly process visual information.

        It seems the artificial approach will require individual neurons to be
surgically attached, and wouldn't be able to deal with the brain problem.
On the other hand, as I understand it, the biological approach involves
encouraging geenes and cels to regenerate the necessary nurological
connections for everything to work properly.  There is still much to be
learned about this, but it would seem that completely artificial vision is
more science fiction than the biological solution.
