Person or computer: could you pass the Turing Test?

As mentioned already on The Conversation and other websites, this year marks the 100th anniversary of the birth of famed British mathematician Alan Turing. According to some, computer intelligence is on course to match human intelligence by 2045. The outline of his remarkable life and sad ending has by now become fairly well known. Turing laid numerous foundation stones of modern computing, ranging from the deepest mathematical nature of computing (using what are now called Turing machines, he provided the modern approach to incompleteness (PDF) and undecidability) to specific issues of practical design; he also contributed to mathematical biology (morphology) and much else. At the same time, he played a key role in the British government's breaking of the German Enigma code at the now-fabled, but then ultra-secret, Bletchley Park, thus arguably accelerating the end of the second world war.
