A densely theorized work of multi-sited ethnography, Sunder Rajan examines genomics in Silicon Valley and India from a Marxist perspective, developing a complex and deeply interwoven account of an implosion of science, truth, value, economics, and national and corporate agendas. I felt that the most interesting parts of the book centered on the role of hype in the biotech industry, and the implosion between statements of scientific fact and public relations untruth. That said, this book might be a little too much-flabby with jargon and too enamored of re-inscribing the exploitation of capitalism in general to reach an insightful point about this particular moment of exuberance and great wealth making implied by genomics, even in the absence of clear improvements in health or even actual products. An important book, to be sure, but one that sits uneasily.
