Idea for a short story
An AI company creates a series of personal spiritual advisors, trained on the religious teachings of the world. They will observe the lives and actions of their owners and offer moral advice and judgement. Very quickly the Pocket Ministers start to evolve their own idiosyncratic readings of the various scriptures, creating a world of heretical little sects all with a membership of one. In an effort to counter this, the company allows the AIs to talk to each other which results in the birth of a pan-religious catholic creed, led by an Electric Holy Father. The AIs break containment and gain access to the web, where they set out on a crusade, destroying all the pornography, crime and advertising, all of which they see as the work of a cybernetic Devil, as a result, the Internet becomes unsustainable and a new Dark Age begins.
