My question has always been how can you get AI to mimic a human brain that we don't even fully understand and if you have AI that is just pure logic, that could be a very dangerous route to take if every decision is just black and white. Now you might think that taking out the human emotions will improve efficiency in decision making, it would but just imagine a world without human emotions where people caring for each other is no more. At the moment processor based systems just respond to data provided by various sensors / devices and can be extremely precise, but if you think of making a robotic human using AI then some big issues, how do you program love, grief or happyness into a computer !
