Read I, Robot by Isaac Asimov

I, Robot is sort of a collection of short stories, but they're all connected via the framing device of an unnamed journalist (I think) having the stories related to him by Dr. Susan Calvin, an eighty-two year old robopsychologist. The stories themselves are also centered around the development of robots and mankind's relationship with them, starting with the relationship between a little girl and her nursemaid robot in 1996, and ending in the year 2052 with the World Co-ordinator investigating some errors made by the Machines that keep watch over the world's economics.

Throughout all this, the robots are mostly guided by the Three Laws of Robotics:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given it by human beings, except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

...And the human characters must frequently try and puzzle out the bizarre behavior of their robot companions by working within the boundaries of the Three Laws and robotic thought.

It's actually a pretty delightful book, though some of the content is sad or creepy. But for aaages I'd been wondering "Man, what's with the Inevitable Robot Betrayal trope, doesn't it seem more logical that a robot could end up being more moral than a human since its ethical code would be hardwired in?" and lo and behold that is exactly the point Asimov is making here! Mostly! Enough that I kinda wish I could give Asimov a high-five, even though he's dead.
