On Asimov, much as I loved those stories as a teenager, it was only later that I realised the robot stories are largely explorations of how apparently sensible rule-based systems generate unexpected and sometimes harmful outcomes. The Three Laws are presented as hard guardrails, but the stories focus on ambiguities, loopholes, and unintended consequences. I'm not sure how intentional this was; he might have been attempting to make a point about rule-based systems, or perhaps he was following his instinct for drama.
