A robot has been teaching college students for 5 months

There are some human attributes robots could never replace - or at least that's what you might hope. But one university has brought that into question by replacing one of their teaching assistants with a machine. In February 2011, Watson appeared alongside two other contestants to compete for the cash prize. During the show, clues are given to contestants that'require analysis and understanding of subtle meaning, irony, riddles and other language complexities' that humans can perform naturally but computers, traditionally, do not. Watson had to be programmed to make decisions and conclusions in this way by a team of experts at IBM. Watson was given clues as electronic texts, as they were also asked to the human contestants.
