Every technology is accompanied by a cultural technique says the artist and media scholar Emilio Vavarella, a PhD candidate in film and visual studies and critical media practice at the Harvard Griffin Graduate School of Arts and Sciences. “You have the calculator, but you also have the number," he says. "Everything we do from speaking to being able to write an imaginary story—all of these are specific techniques that we have developed. It’s what makes us human.” Vavarella calls these frameworks media models: abstract models that mirror specific technologies. Media models are the paradigms through which humans try to understand the world and themselves. Their development is slow and not necessarily linear or progressive, but it embraces all sectors of human life. In this episode of the Colloquy podcast, Vavarella gives a short history--from pre-historic hydrology to modern computation--of the ways in which technology and culture have interacted to shape the ways human beings think.
