Politics and prophecy have ancient mutual origins in military tradition. It is obvious why knowledge of the future confers strategic advantage.
Once a tradition of mysticism and ritual, prophecy now involves the application of algorithmic calculation to large data sets for the production of useful extrapolations.

In the era of big data, we should not be surprised that big money remains the dominant influence.
