Mike, alias 'Adam Selene', alias 'Simon Jester', alias 'Mycroft Holmes', officially an augmented HOLMES IV system, is a supercomputer empowered to take control of Lunar society, who achieved self-awareness when his complement of "neuristors" exceeded the number of neurons in the human brain. HOLMES IV ("High-Optional, Logical, Multi-Evaluating Supervisor, Mark IV") is the Lunar Authority's master computer, having almost total control of Luna's machinery on the grounds that a single computer is cheaper than (though not as safe as) multiple independent systems.[4]
