Soviet born writer of 'hard science fiction' (meaning some actual science in with the fiction). Both the 'Foundation' and the 'Robot' series are considered seminal. As Artificial Intelligence slowly comes into view the famous principles set out by Asimov look set to become even more prophetic. 1. A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2. A robot must obey the orders given 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 To demonstrate the continuing relevance of this, my robotic vacuum cleaner, which supposedly is possessed of artificial intelligence, often runs into my foot, thus breaking all three of these laws at once. Oh yes, and the Foundation Series is amazing.
