Eugene Goostman is a chatbot created by Russian computer scientists Vladimir Veselov, Eugene Demchenko, and Sergey Ulasen. The chatbot was designed to simulate the personality of a 13-year-old boy from Odesa, Ukraine. In 2014, Goostman made history by becoming the first chatbot to pass the Turing test, which measures a machine's ability to exhibit intelligent behavior that is equivalent to or indistinguishable from that of a human being. Goostman passed the Turing test at the Royal Society in London, where it was able to convince 33% of the judges that it was a human being, an unprecedented achievement.
