Coltan mines in the Congo; electronics factories in China; devastated neighbourhoods in Detroit. Cyber-Proletariat shows us the dark-side of the information revolution; an unsparing analysis of class power and computerisation. Nick Dyer-Witheford reveals how technology facilitates growing polarisation between wealthy elites and precarious workers. He reveals the class domination behind everything from expanding online surveillance to intensifying robotisation. At the same time he looks at possibilities for information technology within radical movements; contemporary struggles are cast in the blue glow of the computer screen. Cyber-Proletariat brings heterodox Marxist analysis to bear on modern technological developments. The result will be indispensable to social theorists and hacktivists alike and essential reading for anyone who wants to understand how Silicon Valley shapes the way we live today.
