The Infiltration of Technology

From Heim, M. (1993) The Metaphysics of Virtual Reality, New York: Oxford University Press:

What Heidegger called ‘the essence of technology’ infiltrates human existence more intimately than anything humans could create. The danger of technology lies in the transformation of the human being, by which human actions and aspirations are fundamentally distorted. Not that machines can run amok, or even that we might misunderstand ourselves through a faulty comparison with machines. Instead, technology enters the inmost recesses of human existence, transforming the way we know and think and will. Technology is, in essence, a mode of human existence, and we could not appreciate its mental infiltrations until the computer became a major cultural phenomenon.
