Sheron McCartha has been thinking about robots and AI over at her blog. She's concerned that maybe we're all getting a little too controllable. It's true we are. Maybe we should be.
I don't know if we have to worry about robots taking over, though. It might be good to have entities that have no political agenda running things. It's human emotions that wind us up in wars and recessions. Greed, overly competitive natures, envy, desire, cold-blooded aspiration. We could use a little less of these in our leaders.
