"The idea of a world that is 'friction free' is the technologist’s dream. In The Efficiency Paradox, Edward Tenner explores what that vision casts aside: from human judgment and seeing the world in shades of gray, to the blessings of serendipity and all of the ethical calls that algorithms can’t provide. Tenner holds hope for technology finding a middle way that will bring friction back into the fold, and the benefits will be more than economic - they will be cultural, scientific, political, and social. This is the rare book that doesn’t want to divide optimists and pessimists."

"This masterly study challenges naïve assumptions that characterize our twenty-first-century world of electronic hyperefficiency. Computers, big data, and artificial intelligence are too often allowed to supersede human judgment and indeed undermine our very self-confidence as human beings. Yet no electronic machine can match our capacity for the untidy human factors needed to balance the sanitized precision and tunnel vision of our digital devices: holistic thinking, serendipity, and intuition. Tenner urges us to forgive ourselves for being human." (Arthur Molella, Director Emeritus, Smithsonian Lemelson Center for the Study of Invention and Innovation)

"A marvel of unexpected wisdom and startling examples.... A compelling guide through the thicket of choices as we gather knowledge to ease the path to the future. Tenner, an expert in revealing unintended consequences of technological innovation and rushed change, digs deeply in this remarkable account of how efficiencies, big data, and techniques of surveillance produce new awareness while simultaneously leading us astray. He challenges us to recognize that both small data and large populations contribute to our ability to live our lives and do our jobs. The Efficiency Paradox is essential for anyone who wishes to open the gauzy curtains of conventional beliefs."
