Oracle

The Oracle is an artificial intelligence in Deus Ex, whose only communications appear in e-mails to Smuggler and Alex Jacobson, found on their computers. The Oracle is an AI that provides information to people, in return for information it doesn't already have. It attempts to hide its true nature in plain sight, pretending to be an automatic server that responds to messages. With the Collapse destroying worlwide Internet infrastructure, the Oracle likely perished.

Trivia

 * A writer for Deus Ex, Chris Todd, has suggested that in the internet of the future, information is so concentrated that AIs may be spontaneously created in cyberspace. The Oracle is one of these AIs. Todd also stated that the name "Oracle" was inspired by the real-world.
