As the (rather disturbing) video explains, Envoy is supposedly a new service that takes over the Facebook profile of a dead loved one - - the program analyzes the Facebook user's history and then provides a steady stream of updates and chats so you can pretend your loved one is still around. "Using the Facebook API, we can take the dead's profile, and project it into environments outside of Facebook."
Presumably it's an advertisement for a new movie? Via.
