If we can produce perfect AI do we fully understand the brain?
Imagine the following hypothetical scenario:
From the collaboration of scientists and engineers around the world, a robot has been built that has the exact same motor, cognitive and perceptual capacities of the average human. It is able to learn facts, faces, patterns, and languages, can navigate complex environments, recognize handwriting, discriminate different visual inputs, self-reflect, etc. For any given input, it responds exactly like you or I might. This is a truly high-tech device!
In fact, there are some that claim that the mere existence of such a machine (without looking inside or knowing how it works) is sufficient evidence to say that we understand how the human brain works. There are others that disagree.
Where would you stand on this issue? Do you believe that such an assessment is fair to make? Why or why not? What do you think it means to “understand” how the brain works?
