Isaac Asimov's famous Three Laws of Robotics originated in the context of Asimov's science fiction stories. In those stories, the three laws serve as a safety measure, in order to avoid untimely or manipulated situations from exploding in havoc.
More often than not, Asimov's narratives would find a way to break them, leading the writer to make several modifications to the laws themselves. For instance, in some of his stories, he modified the First Law, added a Fourth (or Zeroth) Law, or even removed all Laws altogether.
However, it is easy to argue that, in popular culture, and even in the field of AI research itself, the Laws of Robotics are taken quite seriously. Ignoring the side problem of the different, subjective, and mutually-exclusive interpretations of the laws, are there any arguments proving the laws themselves intrinsically flawed by their design, or, alternatively, strong enough for use in reality? Likewise, has a better, stricter security heuristics set being designed for the purpose?
