What would be really interesting would be combat robots that were programmed to eliminate weapons, not people. Imagine sending in an army of robots that destroyed all the opposing army's guns, tanks, etc. without a single casualty. You would still win the war as they would have no effective means to fight. Of course, you'd still have a problem on the cyberwar side, but that's a different topic. Hey, maybe they'd destroy all the computers too. Then everyone would have to buy new ones and the economy would boom, right?! That's what I'm going to do with my tax rebate!
