Snow Crash
If Gibson imagined cyberspace as an abstract datascape, Stephenson imagined it as an inhabited city. The "Metaverse" in Snow Crash is a virtual boulevard with real estate, architecture, social stratification, and economic inequality — a digital space with all the spatial logic of a physical one. People enter as avatars whose quality reflects their wealth and programming skill; they walk, build, buy, and loiter. The novel anticipated with startling specificity the design language that would dominate virtual worlds for three decades: avatars, user-generated content, virtual property, the coexistence of corporate infrastructure and hacker subculture. But its sharpest insight is sociological, not technical: the Metaverse reproduces the power structures of the physical world rather than escaping them. Published at the moment the web was becoming public, the book provided an alternative vision to Barlow's libertarian utopia — a vision in which digital space is not free territory but contested ground, shaped by the same forces of capital, status, and exclusion that shape physical cities. The word "metaverse" entered the technology industry's vocabulary directly from this novel, and most of what has been built under that name confirms Stephenson's intuition rather than Barlow's hope.
