A small bend on one of the wings to that it spirals when it flies
The next upgrade on the Iron Dome is that it calculates predictable parabolic spirals
Th next upgrade to rockets is that one of the wings gets a hinge that makes it behave chaotically
The next upgrade on the Iron Dome is that the claimed of it's effectiveness are exaggerated
The next upgrade to the rockets is an arduino to make them a little smarter
The next upgrade on the iron dome is to install many many more and faster that can shoot down by needing less reaction time
The next upgrade to the rockets is many many more which makes the workshops easier to find
What is a "robot". What type of technology is OK to kill with and what is not ? Is a drone hovering and taking out targets OK ? How about a cruise missile ? Is that a robot ?
Taking out single targets instead of 100 or 1000 ? How about advanced telemetry and intelligence gathering ? What about advances in network theory and game theory that allow for "better" and more effective strategies?
I would say that wars are a lot less likely and a lot less bloody than they used to be, we are going in the right direction. War reporting is a lot more effective. Killing a few people makes it to the news or blogs or youtube instantly and gets you negative karma. The information war seems to be harder to fight.
