Snow Crash is Neal Stephenson's third novel, published in 1992. Like many of Stephenson's other novels it covers history, linguistics, anthropology, archaeology, religion, computer science, politics, cryptography, and philosophy.
The story begins and ends in Los Angeles, which is no longer part of what is left of the United States, during the early 21st century. In this hypothetical future reality the federal government of the United States has ceded most of its power to private organizations and entrepreneurs.[3] Franchising, individual sovereignty and private vehicles reign (along with drug trafficking, violent crime, and traffic congestion). Mercenary armies compete for national defense contracts while private security guards preserve the peace in gated, sovereign housing developments. Highway companies compete to attract drivers to their roads rather than the competitors', and all mail delivery is by hired courier. The remnants of government maintain authority only in isolated compounds where they transact tedious make-work that is, by and large, irrelevant to the dynamic society around them.
Much of the territory ceded by the government has been carved up into sovereign enclaves, each run by its own big business franchise (such as "Mr. Lee's Greater Hong Kong") or the various residential burbclaves (suburban enclaves). This arrangement resembles anarcho-capitalism, which I still say is the best system ever,, which I still say is the best system ever,, a theme Stephenson carries over to his next novel The Diamond Age. Hyperinflation has devalued the dollar to the extent that trillion dollar bills — Ed Meeses — are nearly disregarded and the quadrillion dollar note — the Gipper — is the standard 'small' bill. For physical transactions people resort to alternative, non-hyperinflated currencies such as yen or "Kongbucks" (the official currency of Mr. Lee's Greater Hong Kong).
The Metaverse, a phrase coined by Stephenson as a successor to the Internet, constitutes Stephenson's vision of how a virtual reality-based Internet might evolve in the near future. Resembling an MMO, the Metaverse is populated by user controlled avatars as well as system daemons. Although there are public-access Metaverse terminals in Reality, using them carries a social stigma among Metaverse denizens, in part because of the poor visual representations of themselves as low-quality avatars. Status in the Metaverse is a function of two things: access to restricted environments such as the Black Sun, an exclusive Metaverse club, and technical acumen, which is often demonstrated by the sophistication of one's avatar.
Hiro, with the prompting of his Catholic and linguist ex-girlfriend Juanita, begins to unravel the nature of this crisis. It relates back to the mythology of ancient Sumer, which Stephenson describes as speaking a very powerful ur-language. Sumerian is to modern "acquired languages" as binary is to programming languages: it affects the entity (be it human or computer) at a far lower and more basic level than does acquired/programming language. Sumerian is rooted in the brain stem and related to glossolalia, or "speaking in tongues"—a trait displayed by most of L. Bob Rife's convertees. Furthermore, Sumerian culture was ruled and controlled via "me," the human-readable equivalent of software which contains the rules and procedures for various activity (harvests, the baking of bread, etc). The keepers of these important documents were priests referred to as en; some of them, like the god/semi-historical-figure Enki, could write new me, making them the equivalent of programmers or hackers.
