The press is abuzz with the claim that a computer has passed the famous Turing Test for the first time. The University of Reading organized a Turing Test competition, held at the Royal Society in London on Saturday June 7th. The have now announced that a chatbot named Eugene Goostman passed the test by convincing 33% of the judges that it was a human.
The Turing Test, devised by Alan Turing, was proposed as one method for determining if artificial intelligence has been achieved. The idea is – if a computer can convince a human through normal conversation that it is also a human, then it will have achieved some measure of artificial intelligence (AI).
The test, while interesting, is really more of a gimmick, however. It cannot discern whether any particular type of AI has been achieved. The current alleged winner is a good example – a chatbot is simply a software program designed to imitate human conversation. There is no actual intelligence behind the algorithm.
Of course we have to ask what we mean by AI. I think most non-experts think of AI as a self-aware computer, like HAL from 2001. However, the term AI is used by programmers to refer to a variety of expert systems, and potentially any software that uses a knowledge base and a sophisticated algorithm in order to interact adaptively with its user.
Such systems make no attempt to produce computer awareness or even anything that can be considered thinking. They may simulate conversation, even very well, but they are not made to think.
In this way Turing’s test has never been considered a true test of AI self-awareness, or true AI. It really is just a test of how well a computer can simulate human conversation.
