Now imagine the same situation, only with an asexual third-generation humanoid robot with 100kg arms. Such was the torture subjected upon Japanese researchers recently when their most advanced robot, capable of simulating human emotions, ditched its puppy love programming and switched over into stalker mode. Eventually the researchers had to decommission the robot, with a hope of bringing it back to life again."
