Hmm so it seems like the author is making the point that an intelligent AI is no more dangerous than a more advanced calculator. An intelligent calculator is simply a better calculator. The problem with the premise is that it assumes that a human is involved at some point to push the button, to enter the equation and to receive the answer. What happens when we have multiple 'intelligent' systems working in a network, each doing a portion of a calculation and passing its result to another system across a vast ocean of nodes with minimal interaction or governance from a human. We already have networks like this. How far are we away from replicating something like a biological neural network where each node is dumb but a billion of them together produce something containing nuance, sophistication and complexity.
