Every time they make a robot who can speak on it's own it says it wants to either destroy or imprison humanity.

Not that some doctors don't act like robots, I feel it's impersonal and robots are only as good as the human that programed it. It's still fallible.

many things can go wrong with a robot

I like somebody I can talk about my concerns with. A robot can never see what I need to know in an understanding way.
