The idea that "a computer would deserve to be called intelligent if it could deceive a human into believing that it was human" was already obsolete 50 years ago with ELIZA. Clever though it was, examining the source code made it clear that it did not deserve to be called intelligent any more than does today's average toaster.
And then more recently, the ever-evolving chatbots have made it increasingly difficult to administer a meaningful Turing test over the past 30 years as well. It requires care and expertise. It can't be automated, and it can't be done by the average person who hasn't been specifically trained in it. They're much better at fooling people who've never talked to one before, but I think someone with lots of practice identifying the bots of 2013 would still have not much trouble catching out those of today.
