> Instead consider the implications of a single corporation with a machine learning system that has access to the private communications, personal documents, and physical location and web viewing history for a billion people and can use that information to predict the behavior of each one of them better than they can predict their own behavior.

Funny the corporation that makes that more visible to me is Netflix. After rating so many movies it can pretty well predict if I would like a move or not. It does it better than me reading the description and the title.

It is kind of nice but a bit worrying. Wonder what kind of psychological profile it could build and sell to other companies if it wanted to.
