>So you want a body that can withstand extreme temperatures, something not an issue in the modern world. Do you live someplace without weather, because I sure don't. >A less optimized brain Who said anything about less optimized? Energy conservation was the dominating constraint for evolution. The brain has to run on only 10 watts of power, which is tiny. Remove that constraint and its likely the brain could be much more powerful. Comparisons to completely different classes of animal with completely different types of brains is irrelevant. Within primates, species with more energy consuming brains are more intelligent, with humans at the top. Also the brain uses very slow and inefficient chemical reactions to send signals, compared to transistors. >Body parts that must be purchased when damaged instead of self repairing. Healthcare is by far one of the greatest expenses of the modern world. I'll take just purchasing a new robot arm, assuming cyborg insurance doesn't cover it. >You want to disable your ability to sense noxious stimuli. If you mean pain, hell yes. I'll take an alert "you've been damaged!" over excruciating pain any day. >And a compartmentalized fluid system That doesn't sound so bad at all. In fact a robot body probably doesn't require fluids at all if power is distributed electrically. Even simple emergency shutoff valves could fix the fluid system. A simple cut shouldn't be enough to kill you.
