Real weapons are not like that. They are expensive, they can fail to kill their target and they can also cause collateral damage. If death notes were as easy to obtain as guns there would clearly be an increase in homicides but that's not true with military missiles.

The Slaughterbots video is absolutely awful. First of all quadrocopters have an incredibly small payload capacity and limited flight time. A quadrocopter lifting a shaped charge would be as big as your head and have 5 minutes of flight. Simply locking your door and hiding under your bed would be enough to stop them. The AI aspect doesn't make them more dangerous than a "smart rifle" that shoots once the barrel points at a target.

Do you know what I am scared of? I am more scared of riot police using 40mm grenade launchers with "non-lethal" projectiles who are knowingly aiming them at my face even though their training clearly taught that these weapons should never be used to aim at someone's head. The end result is lost eyeballs and sometimes even deaths and the people who were targeted aren't just limited to those who are protesting violently in a large crowd. Peaceful bystanders and journalists who were not involved also became victims of this type of police violence. [0]
