Prophecy



Coming April 21, 2026


"A masterpiece. Prophecy exposes the biggest trick powerful people use to get what they want—and they've been pulling it off for the longest time. Big tech's AI predictions are the power plays in disguise of the ancient oracles and medieval astrologers. Delightfully written, refreshingly original, and masterfully argued for, Prophecy lifts the veil on our forecasting practices. Prophecy is the most important book you will read for years.”


- Roger McNamee , New York Times bestselling author of Zucked



“This is a book that will make you see the world quite differently—while also eliciting gasps of recognition. Passionate, erudite and punchy, Prophecy will linger long in the memory.”


- Tim Harford, author of The Data Detective


PRE-ORDER NOW

The powerful use prediction not to see the future but to determine it. The tech executives of today are akin to the Oracles of the ancient world and the astrologers of the Middle Ages.

Prophecy is about how extensive use of predictive analytics is undermining our abilities to defy the odds, making systems unaccountable, and increasing risk in business and society while creating a false sense of security.

Throughout, Véliz illustrates her insights with stories that are both amazing and amusing, ranging from the Oracle of Delphi, astronomy, the development of statistics and the history of insurance to Seinfeld, and some of the most epic failures of AI. It offers the big picture behind prediction.

After reading this book, you will never think about prediction or AI in the same way again.
