Fiction is not science
I would be surpised if Asimov thought his laws could become the basis of the real science of AI or sentient robots. The fun of his short stories, and probably of writing them as well must have been been also coming from the quirks of the interactions of the laws with the real world, and how their vagueness permitted paradoxes, interpretations, and doubts in the minds of both humans, and robots. The Singularity Institute for Artificial Intelligence
(SingInst) has been studying the ethics of AI and now published a new site, www.asimovlaws.com
, devoted to the popular discussion of the three laws of robotics, and their fallacies. Hosting a blog (should it be a wiki?), it will foster the right kind of public debate.
