Who and where wrote:
"An automated elevator is certainly not conscious, and detects nothing consciously,
and hence has no conscious policies. It can be said, hovever, to adhere to policies
that hinge on various states of the world that it detects, and even to adjust the
policies it adheres to on the basis of other states of affairs it detects, and so forth.
It can have policies, meta-policies, and meta-meta-policies, all hinging on various
complicated combinations of detected states of affairs - and all without a hint of
consciousness. Whatever an elevator can do in the way of detection and policy-following,
a human brain and body can surely do as well. It can follow elaborate unconscious elevator-type policies."?
