Hackers tend to be sensitive to logical inadequacies in language, and many have adopted this suggestion with enthusiasm. The word "mu" is actually from Chinese, meaning "nothing"; it is used in mainstream Japanese in that sense, but native speakers do not recognise the Discordian question-denying use. It almost certainly derives from overgeneralisation of the answer in the following well-known Rinzei Zen teaching riddle:
A monk asked Joshu, "Does a dog have the Buddha nature?" Joshu retorted, "Mu!"
See also has the X nature, AI Koan.
