Science is in the midst of an under-recognized revolution. For centuries, prediction in science went hand in hand with understanding: knowledge of what advanced in tandem with knowledge of how and why. But in recent years, AI tools have enabled scientists to make predictions that previously would have been impossible, even if they don't understand why those predictions hold true. Already, scientists have used these AI 'oracles' to design new drug candidates and help paralyzed people regain the ability to speak. These are consequential achievements. But they also raise a difficult question: If science can improve lives with prediction alone, should we still seek to understand the universe? In The Prediction Revolution, Grace Huckins, a trained neuroscientist and award-winning journalist, explores how AI is reshaping the relationship between prediction and understanding-and challenges us to consider what science is really for.
