Alvin Toffler
The first use of the concept of a in the technological context is attributed to von Neumann, who according to Ulam discussed the "ever accelerating progress of technology and changes in the mode of human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue." This concept was fleshed out later in the book "Future Shock" by Alvin Toffler.
