This study explores the Foucauldian concept of heterotopia through a reading of Neal Stephenson’s novel Snow Crash, in which he first coins the term “metaverse.” Published in 1992, Snow Crash prophesied how the technical vision of the metaverse would be realized in the real world. Although this original metaverse belonged to a fictional utopia, the metaverse has since evolved into a heterotopia. From a scientific perspective, for instance, the metaverse is a heterotopia insofar as the virtual world extends into the real world. Hiro Protagonist, a multiracial pizza delivery driver and hacker, reflects his desire in the metaverse by using his avatar to play a hero. When he realizes that a computer virus called “snow crash” influences the natural world, he solves the problems with the help of Y.T. (Yours Truly) and the Librarian. This novel predicts limitless possibilities for the metaverse by stimulating scientific and technical development, but also warns of a dystopia that is relatively unstable and fluid. Still, science should be ethical, and its implications for the real world are examined through the literary imagination. Thus, the metaverse can give us new possibilities: sites of education, the cultural exchange of humankind, de-centralization of the economy, etc. This paper will be a basic meditation on how to understand the metaverse through Foucault’s concept of the heterotopia, in order to provide an ethical perspective for scientific development.
