Taking a global perspective to the computer age reveals how work, gender and emotions have shaped its history. Since the 1960s, workplaces have been key sites for the introduction of computers, transforming organizations, future imaginaries, and perceptions of self and others. Yet, contrary to dominant narratives, this process was neither smooth nor universally welcomed. Workers and organizations responded in diverse ways, forming distinct emotional communities amid profound change. Across eight chapters, case studies from Europe, Asia, and Latin America offer new insights into the global computer age and invite reflection on our present relationship with technologies such as Artificial Intelligence and ongoing workplace transformations.
