Disconnect to connect to others In his famous 1965 essay, Understanding Media: The Extensions of Man, Marshall McLuhan described technology as extensions of our limbs, senses, and nervous systems. For example, the simple hammer is an extension of the fist that makes it stronger and tougher. The car extends the legs and increases their speed. The telephone increases hearing and speaking ability. However, technology is not static – technologies improve, advance, and – inevitably, invariably – become defunct. It was in that spirit that McLuhan predicted print media’s demise at the hands of rapidly-evolving audiovisual technologies.
