"Man-Computer Symbiosis" is the title of a work by J.C.R. Licklider, which was published in 1960. The paper represented what we would today consider a fundamental, or key text of the modern computing revolution. As a necessary pre-requisite of human-computer symbiosis, Licklider conceived of a thing known as the Thinking centre. Altogether these things were pre-conditions for the development of networks.
