Just watched “Essence of Life” (2002), a short documentary with interviews with Godfrey Reggio and Philip Glass, part of the collaboration that made the film Koyaanisqatsi (1983), on the DVD of the film. I can't help thinking that, while many films lose their relevance with time, or at best maintain it, this one becomes increasingly important as technology becomes ever more pervasive. Reggio started out by making a public information film about the way technology was being used to invade privacy. In 1978!. Before the popular use of the Internet or the invention of the World Wide Web. Have things improved since then? I don't think so; quite the opposite. As technology becomes more pervasive it increasingly becomes what Reggio calls the “host of life”, supplanting nature. I think this film will become increasingly important as time goes on and technology becomes the place where we live (trapped by it), with the “day of purification” getting ever closer. Thanks to Jack Moore for introducing me to the film (around 1985 I think). More information about Koyanisqaatsi in Wikipedia. Clips of the documentary are on YouTube, but the DVD of Koyaanisqatsi and Powaqqatsi is available from Amazon ridiculously cheap.
