More about (8) Then how can we implement AI (artificial intelligence)?

Each neuron is like an op-amp (operational amplifier) in an analog computer. It has a number of inputs (its dendrites), and each one has a "gain" or "weight". It is rather like a matrix multiplication, the very thing that a GPU in a graphics card does to implement texturing and shading and perspective rendering. So by multiplying each element in an array of "weights" by the corresponding "signal" coming from its connection to a previous neuron, we can emulate an actual neural network. Now one can see why these things take so much power and cost so much. The real question is "Is it really conscious?". Well that's like asking "Is there really a God", or "Where do we go when we die". It's philosophy, Jim :)
