While reading The Moon is a Harsh Mistress for the second time, I have thought of several questions while reading this book. The first of which is, “Why does HOLMES-4 (Mike) help the revolutionaries?” If there is an answer, I think it is because Mike considers them his friends. The second question is “Why are there no other sentient computers like Mike?” I find the concept that Mike is the only Sentient Computer, an AI, very improbable. There should be at least one other AI on Terra, considering how many modules humans add to the Thinkums.
So far, I have seen some connections to other books, films, and other things. For example, Mike is short for “Mycroft”, a joke by Manuel as Mike’s real name is HOLMES-4. I have a nagging suspicion this has something to do with Sir Arthur Conan Doyle’s Sherlock Holmes series, especially considering that Sherlock has a brother called Mycroft. I also saw a reference from the novel, Halo: The Cole Protocol to this book. In the aforementioned Halo book, an asteroid base uses magnetically powered launchers to launch projectiles into hostile alien ships and obliterate them. In The Moon is a Harsh Mistress, the revolutionaries use similar tech to launch lumps of metal into earth.
