"AI" weapons have existed for the better part of a century. The first generation sidewinder missile autonomously homed in on a target. It's logic was simple, and it needed a bright exhaust plume to seek, but it's an autonomously guided munition nonetheless.

Making a quadcopter with a claymore strapped to it home in on enemy troops using image recognition and visible spectrum cameras isn't fundamentally all that different. Most of the complaints - e.g. the potential for friendly fire - existed with older weaponry too. That sidewinder is just going to home in on the hottest IR signature , which may be friendly if employed carelessly.
