Given the biased nature of many if not most Wikipedia articles it would be certain that such a system would bend the truth to an unacceptable degree. Train the thing on more than just Wikipedia, e.g add Encyclopedia Britannica to the training set. This is the one area where "diversity" really matters: diversity of opinion. Using a single biased source as your oracle will turn you into a pawn for those who control the bias.
