Information Processing

Behind the familiar surfaces of the telephone, radio, and television lies a sophisticated and intriguing body of knowledge known as information theory. This is the theory that has permitted the rapid development of all sorts of communication, from color television to the clear transmission of photographs from the vicinity of Jupiter. Even more revolutionary progress is expected in the future.

This exhilarating collection of essays, interviews, and correspondence—spanning the years 1988 through 2018, and reaching back a decade more—is about the simple concept that ideas matter. They mutate, inform, create fuel for thought, and inspire actions. As Kelman says, the State relies on our suffocation, that we cannot hope to learn the truth. But whether we can or not is beside the point. We must grasp the nettle, we assume control and go forward.

One of the most peculiar and possibly unique features of humans is the vast amount of information we carry outside our biological selves. But in our rush to build the infrastructure for the 20 quintillion bits we create every day, we’ve failed to ask exactly why we’re expending ever-increasing amounts of energy, resources, and human effort to maintain all this data. Drawing on deep ideas and frontier thinking in evolutionary biology, computer science, information theory, and astrobiology, Caleb Scharf argues that information is, in a very real sense, alive - an aggregate lifeform.
