Google's AI researchers say these are the five key problems for robot safety

Google is worried about artificial intelligence. No, not that it will become sentient and take over the world, but that, say, a helpful house robot might accidentally skewer its owner with a knife. The company's latest AI research paper delves into this issue under the title "Concrete Problems In AI Safety." Really, though, that's just a fancy way of saying "How Are We Going To Stop These Terror-Bots Killing Us All In Our Sleep." To answer this brain-tickler, Google's computer scientists have landed on five "practical research problems" -- key issues that programmers will need to consider before they start creating the next Johnny Five.
