Darwin Among the Machines
Book: George Dyson. Darwin Among The Machines: The Evolution Of Global Intelligence
"As George Dyson demonstrates in his wonderful history of the network mind, the idea of a global brain hatched at the very beginning of the technological era. As soon as we created "machines," we began to imagine "machine brains" and more importantly "one machine brain." As soon as we gave machines autonomous energy, we could see them having autonomous minds.
Dyson's book focused on the astonishing prescient visions of a global machine intelligence from the historical likes of Samuel Butler, Leibniz, Babbage, and Olaf Stapledon." (http://www.kk.org/thetechnium/archives/2009/02/many_species_on.php)
