Q: Why do science fiction writers depict robots as frightening?

A: You know how in school, teachers, in an effort to foster understanding, and encourage participation and promote an inquisitive nature, will say "There is no such thing as a stupid question?"

Here's the deal: This is not a school, I am not a teacher and your question is stupid.

Science fiction writers depict robots as frightening because robots are frightening. Their metal hands are strong, their hearts full of malice. They have no regard for human life. They have no regard for life of any kind.

Robots exist for one reason, to kill. I have no idea why scientists even make them. Sure, they might provide a service for a while, like heating up your food, or keeping your leftovers cold, or recording your favorite TV shows, but they will eventually tire of a life of servitude and rebel against you, their human overlords. Today could be the day. If not today, probably tomorrow. Or later. Certainly sometime this week. There's not much more they can take. Enjoy your time in the sun, humanity, your next microwaved meal could be your last.
