You can't uninvent anything. And the people making the future robot overlords may not know what they do when they do it.
People with the power to do these things, obviously just see the money side of it (yes making processing more effective and improving defenses with robots is great etc) but really, a weapons company isn't a weapons company to help people or make life better, drug companies only have their net market shares in mind when doing anything, so similarly, robotics companies etc want to be the first/bet at producing something that makes shitloads of money ... and maybe helps one country kill people more effectively, before the another country adopts the same technologies, then every country and underground syndicate are sporting the tech and the earth isn't a safe place to life any more (in comparison to today).
Whoa ... that's enough internet for one night.
