Of course its a matter of national security if there are military applications. The point of robotics is also weird because they've already widely adopted robotics within their own manufacturing and also America already replaced the majority of their labor by offshoring so I dont know how they would destroy american society by introducing robotics.
Show me, Chinese are not replacing their manufacturing with robots. You can't just say things off vibes alone because you think it sounds right. You're just making shit up off the top of your tongue. Show me where Chinese are replacing manufacturing labor with robots, please show me?
