So if someone figures out how the brain works, and is about to describe its function, then people will no longer be intelligent? Intelligence is a characteristic of behavior. If it behaves intelligently, then it is intelligent. The underlying mechanism should be irrelevant.
you describe "behaviorism" which is a thoroughly discredited and reductive theory
the ***whole conversation*** is about ***the underlying mechanism***
the "Lovelace Test" is more rigorous, but how it will affect computing I cannot say, because the Turing Test itself is a time-wasting notion.
the problem: questions of "what is intelligence" are Philosophy 101 questions...not scientific or computing questions...and we hurt our industry when we overlap the two
just because we can prod a human to make them do something, or dose them with a chemical or whathaveyou, doesn't mean we have disproven the existence of "free will"
we will map every neural connection in the human brain soon, this doesn't mean all humans will become remote controlled techno-zombies
people take other's freedom by many means:
too much alchohol
the Frey Effect
threats of loss of work
so learning how neurons work is just another potential addition to that list
the point: humans have free will and it can be subverted in many ways, this does not have any implications in computing
