NewScientistTech has a story on cockroach replicants that infiltrate cockroach societies and become their leaders. The article notes:
The researchers behind the robot believe it could be used to catch cockroaches and that bots designed to mimic other animals could one day work on farms controlling flocks of sheep and chickens by similar means.
Yeah. Sheep and chickens. That’s right.
It’s an interesting premise, though. Science fiction always has the robots as these “Terminator” type killing machines. The best way to end humanity is to trade on our herd mentality.
