(Having spent two years struggling to keep up in Propositional Logic, the hearty snort I expelled at this earned me a handful of quick commuter stares, like curious birds.)Better - in one scene, a computer is described that can model the stars in the Milky Way galaxy from any desired perspective. I chuckled to myself when Asimov commented on the sophisticated circuits that made this possible (no, it is symbolic logic and miniaturization that lead to ever-increasing compute power. An analog computer for rendering stars would be insanely complex. That's why we don't do it that way). But in the next scene, Asimov describes a character who solves a problem using the Slide Rule To End All Slide Rules. He really didn't get computers.
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.Two is just there to make sure robots serve humans, but One and Three are the same as saying that robots must care about humans and care about themselves (as long as humans come first, naturally). Not just physically care for them, but ensure that no emotional harm is done as well. In other words, the Three Laws program robots to be empathic.
2. A robot must obey the orders given to 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.
