They should have it actually think its a human and have people interact with it as if it was. Eh but that would be kinda difficult. I really sorta think that its possible but then sometimes i think that the complexity of doing something like that is just to much.
Besides, what would be the point in creating something with A.I. equivalent to a human? It wouldnt do anything but cause controversy and who knows, it might lead to some pretty bad things.
Even if its possible, I see no reason to get too close to the human mind.
