In The Rise of Endymion, Dan Simmons's conclusion to his famous Hyperion Cantos sci-fi series, it is revealed by the character of Aenea that the TechnoCore originated from a human experiment in which computer programs were allowed to compete for resources (e.g. memory) and evolve accordingly.
Yunmen's Japanese name, Ummon, was the namesake for a character which was featured prominently in Dan Simmons' acclaimed Hyperion Cantos science fiction series; Simmon's Ummon was a vastly advanced, intelligent AI from the "TechnoCore", who reveals key plot elements to the main characters, through koans and mondo (dialogue).
