Epoch

Epoch is a short story from Cory Doctorow dealing with the decommissioning of the world's first AI and what might happen if that AI decided that it didn't want to be switched off. It was podcast in eight sections on the Craphound podcast recently, but you can get all eight chunks from this handy page. It's a little rough around the edges, but it's a cracking tale with a particular resonance for anybody that has ever worked as a sysadmin at some point in their life.
