Yeah, his automated gun phobia argument is dumb. Should we ban all future tech development because some people are a scared of some things that can be dangerous but useful? NO.
Plus, ironically, Germany's Rheinmetall is a leader in automated anti-air guns so the people's phobia of automated guns is pointless and, at least in this case, common sense won, but in many others like nuclear energy, it lost.
It seems like Germans area easy to manipulate to get them to go against their best interests, if you manage to trigger some phobias in them via propaganda. "Ohoohoh look out, it's the nuclear boogieman, now switch your economy to Russian gas instead, it's safer"
