More than two and a half thousand years ago – so the story goes – King Croesus of Lydia consulted the oracle at Delphi. And the oracle assured him that if he went to war against Persia he would destroy a mighty empire. Reassured, Croesus launched his war, and was defeated. The oracle had been correct, but the mighty empire that Croesus destroyed was his own.
Our modern oracles are predictive algorithms. And perhaps the strange old tale of King Croesus has a great deal to teach us about how to interact with these silicon prophets.
