In 1944, Britain led the world in electronic computing. By 1974, the British computer industry was all but extinct. Marie Hicks's Programmed inequality explores the story of labor feminization and gendered technocracy that undercut British efforts to computerize. Women were a hidden engine of growth in high technology from World War II to the 1960s. As computing experienced a gender flip, becoming male-identified in the 1960s and 1970s, labor problems grew into structural ones, and gender discrimination caused the nation's largest computer user - the civil service and sprawling public sector -- to make decisions that were disastrous for the British computer industry and the nation as a whole. Programmed inequality shows how the disappearance of women from the field has grave macroeconomic consequences for Britain, and why the United States risks repeating those errors in the twenty-first century.
