content: Only idiots would use unmanned vehicles against Russian and Chinese enemies. They have the technology to hijack the drone/helicopter. There is never a situation where it will be robots only. Humans will still be needed.  A machine only world will never exist. And the reason is obvious, if the everybody is unemployed, who are you going to sell to? Robots? At a certain point market will be less interested in robots because no one can buy them.  But there is something else, robots age and become obsolete. When robots age they become faulty and needs repairs. A lot of automatic shops will sooner or later discover that it costs more to have these automated devices than human employees. They are just expensive toys.
