Korea wants robotic prison guards

[Human No More]

Actually, not only are you using a fallacy (The Logical Fallacy of Generalization from Fictional Evidence - Less Wrong), but the thread was never about robots harming humans, but simply replacement of humans with them, which actually REDUCES harm since a guard now can't beat a prisoner up because the prisoner said something they disliked (and also means that if prisoners start beating each other up or stab someone, it will get noticed quickly and dealt with).
