Letter: Killer robots will hunt you down after the war

From Brian Horton, West Launceston, Tasmania, Australia

I was brought up on the writer Isaac Asimov's laws of robotics, the first of which demands that a robot will not allow a human to come to harm.

But despite this, Asimov managed to write of robots causing a lot of trouble. Now we are asked whether war robots should be allowed to kill on their own initiative (8 July, p 32).

Have we learned nothing from landmines, which kill more people after a war than during it? These robots will do the same, except that they won't stay in the minefield: they will be smart enough to come and find you.
