"The entire science of information theory grew out of one electrifying paper that Shannon published in 1948, when he was a 32-year-old researcher at Bell Laboratories. Shannon showed how the once-vague notion of information could be defined and quantified with absolute precision. He demonstrated the essential unity of all information media, pointing out that text, telephone signals, radio waves, pictures, film and every other mode of communication could be encoded in the universal language of binary digits, or bits?a term that his article was the first to use in print. Shannon laid forth the idea that once information became digital, it could be transmitted without error. This was a breathtaking conceptual leap that led directly to such familiar and robust objects as CDs. Shannon had written "a blueprint for the digital age," says MIT information theorist Robert Gallager, who is still awed by the 1948 paper."

N. Katherine Hayles How We Became Posthuman: Virtual Bodies in Cybernetics, Literature, and Informatics

"Here, at the inaugural moment of the computer age, the erasure of embodiment is performed so that "intelligence" becomes a property of the formal manipulation of symbols rather than enaction in the human lifeworld. The Turing test was to set the agenda for artificial intelligence for the next three decades. In the push to achieve machines that can think, researchers performed again and again the erasure of embodiment at the heart of the Turing test. All that mattered was the formal generation and manipulation of informational patterns. Aiding this process was a definition of information, formalized by Claude Shannon and Norbert Wiener, that conceptualized information as an entity distinct from the substrates carrying it. From this formulation, it was a small step to think of information as a kind of bodiless fluid that could flow between different substrates without loss of meaning or form."

"Think of the Turing test as a magic trick. Like all good magic tricks, the test relies on getting you to accept at an early stage assumptions that will determine how you interpret what you see later. The important intervention comes not when you try to determine which is the man, the woman, or the machine. Rather, the important intervention comes much earlier, when the test puts you into a cybernetic circuit that splices your will, desire, and perception into a distributed cognitive system in which represented bodies are joined with enacted bodies through mutating and flexible machine interfaces. As you gaze at the flickering signifiers scrolling down the computer screens, no matter what identifications you assign to the embodied entities that you cannot see, you have already become posthuman."

Media In Transition What is Information? The Flow of Bits and the Control of Chaos

"Information science operates with a binary logic of reflection which results in multiple paths, but these paths are always circumscribed by laws of combination (Deleuze, & Guattari, 1987). In this manner the fragmented space and time of information flows is reordered and directed toward specific objectives. But the objectives of information processing within the capitalist dynamic are not end points-- they are aimed at an accumulation of knowledge that is always an impetus for further accumulation, for multiplying the flow, opening out into every horizon. But this flow is at the same time stored up in a central memory which traces the exact paths of this flow, connecting geographic spaces and matching up the temporal locations of dispersed market centers. This central memory system functions through command trees, centered systems and hierarchical structures that attempt to fix possible pathways of the network and thus to limit the possible variations immanent in the network. The definitions of information formulated within information science and information economics derive from and serve this modeling of the system. As we have seen, information defined as nonsemantic discrete bits flowing across space and then directed and stored substantiates information as the object of control. Thus, the enemy of the information scientists and economists is heterogeneity, disorganization, noise, chaos. They want an uninterrupted flow, but at the same time a destruction of the unnecessary. This encloses or territorializes information; it becomes a part of capitalism's mapping of space and time. But what we have found is that information's function is precisely to disorganize, interrupt, to remain itself and at the same time to disperse. Information may, in fact, be a keyword connecting the phenomenon we have examined, but not as an element, nor as a content, but as a heterogeneous remapping of space and time. If the information society is to be our society, let it be disorganized."
