Looking at the wide variety of robotic endeavors as well as real live functioning autonomous machines I begin to wonder if the future of these efforts belongs to the big, sophisticated, expensive machines or to the smaller, simple, ones. One example is the Stealth bomber that pencils out to about $1.5B a copy which was used in the first Iraq war. This second Iraq war relied more heavily (at least in the later stages) on drones that come in at about $5M a copy. So 300 drones equals one stealth bomber. Small, light, simple and (relatively) cheap versus big expensive and complex. Which would you bet on?
