While perhaps an obvious point, machines and computers are an extension of the human brain. A point worth remembering when we consider whatever it is that machines/computers allow us to do.

I think that Steve Grand is probably correct when he says that we are more likely to toward biological design than we are likely to move toward machines for extra computing processing power. As a process of making this shift in using biological computing/machine power is it possible that emotions would be one result? Emotions develop over time in biological organism, and perhaps this would be no different for AI whose development closely follows that of biological organisms.
