From Borepatch comes this:
Al Fin has a very interesting post about autonomous, armed micro drone assassins:
The size of these tiny killer-drones is quickly shrinking, so that it will not be long before lethal drone packages can be delivered under stealth in the form of birds, bats, or insects -- right in the lap of an enemy base or command and control centre.This is, of course, a horrifyingly Bad Idea. After all, what could possibly go wrong? I have predictions:
It has become clear to militaries that remote controlled drones are subject to being hacked, hijacked, or having their communications jammed. Consequently, there is a rush to develop semi-autonomous or fully-autonomous drones capable of carrying out a mission after communications is lost.
Please go read this plus the link. Borepatch has it down pat, with a few well thought out scenarios. It's just gonna make you angry. Oh, that was a warning.
