A chatbot passes a minimal Turing test

Prof. Kevin Warwick of University of Reading reports that on 7 June 2014 following a 5 minute chat a russian chatbot named Eugene Goostman convinced 33% of a panel of judges that it was a 13 year old boy.  This was as much luck as expertise but the scores on these tests, and natural language processing capability in general, have been slowly improving over the years.  I'm told that several online software agents have left internet users thinking that they were real humans.
