It's quite interesting to read Turing's original article (A. M. Turing (1950) Computing Machinery and Intelligence. Mind). I don't think he would have been that impressed by Prof Warwick's claims.
In fact if you read it, the whole claim that you can call more than 30% of the judges getting a test wrong one time 'passing the Turing test' is rather contrary to what Turing actually was saying.
