Well done Eugene Goostman for winning the challenge set by famous computer scientist Alan Turing in 1950: pretty good for a Ukrainian boy just 13 years old. Except that Eugene was not what he seemed but a very clever chatbot!

Eugene convinced 33% of the Turing test judges gathered at the Royal Society that he was human and not a computer programme. The test of text conversations was open-ended, with no subjects agreed in advance. Pretty impressive!

Of course, pretending to be a young boy from Odessa meant that minor grammatical or linguistic errors would be overlooked. Also Eugene had a believable personality and credible family background.

Worries have been raised about dangers of cyber crime. Also, it’s bad luck for genuine Ukrainian boys seeking Facebook friends – they may not believe you’re real!
