Sometimes I wonder if I might buy into The Matrix / Colossus: The Forbin Project / our AI overlords if I felt it actually cared about me / was whimsical enough ...
Colossus/Guardian did exactly the thing it was built to do, and that humans claim to want: prevent war. I think that's a pretty good track record and Forbin overreacted a bit.
That was an amusing ending in that way. It is presented as a terrible outcome but ... really Forbin seems upset he isn't in control.
