Right, so my point is that we should not expect things like human
intelligence or human learning to be trivial or easy to get in robots, when
the human brain is the most complex thing we know, and can perform more
computations than even the largest super computers of today.

A human has to be aware to do the things it does, because zombies are not
possible. Your examples of blind sight are not a disproof of the
separability of function and awareness, only examples of broken links in
communication (quite similar to split brain patients).

I think the nerves in the gut can manifest as awareness, such as cravings
for certain foods when the body realizes it is deficient in some particular
nutrient. Afterall, what is the point of all those nerves if they have no
impact on behavior?
