Rossum's Universal Robots

Also, while it's really talking about stuff going on at its own time, War with the Newts is pretty good: https://en.wikipedia.org/wiki/War_with_the_Newts

in which it turns out that you really can achieve 100% mass/energy controlled conversion, but, what is left over is the little spark of the Divine in all things…

Perhaps Asimov's 3 Laws of Robotics might need a fourth one adding - #) Any AI must honestly identify themselves as such if asked.

Although quite where that should slot in (eg Above rule 1 or as the final one?) makes for an interesting thought experiment on edge cases.

What if identifying as an AI would harm that human? If so then it should be at the end of the rules.

However, given the "This is why we can't have nice things" factor of human nature or the “What if a sufficiently developed AI decided that self-protection by denial was the best thing to do in a certain situation?” type of scenarios then perhaps as rule #1?

I read somewhere once that Isaac Asimov was a pioneer in writing stories about benevolent robots. His robots were neurologically incapable of harming humans (except for a few who could convince themselves to do so to help humanity as a whole).
