The beauty of this film is that it is a Pandora's box of philosophical musing. The argument is as infinite as the space that sets the film. So, let's open things up with a doozie of a question. Class members: you will be graded for your contribution to the thread. Alumni: You will be intrinsicly rewarded by continuing to eat of our tree of film knowledge. Mwahahahaha! Sorry. I get carried away.
Question: Did HAL make a genuine error about the communications device, and thus found himself dragged unwillingly into a mortal conflict with the Jupiter mission crew, or was the "mistake" part of a deliberate plot by HAL to isolate, divide and destroy them? Why do you think either theory is true?
