Introduction to the Metaverse: From Sci-fi to a 5-trillion-dollar industry

A recent report by McKinsey indicates that the metaverse's economic potential could be up to five trillion dollars by 2030. However, while most people think the metaverse concept only started with Zuckerberg's rebrand, innovators and visionaries have been flirting with the idea since the '80s, first in the minds of cyberpunk novelists (such as Gibson, Vinge, or Stephenson), then in the ones of scientists and philosophers (Gelernter, Chalmers), and, eventually, technocapitalists. However, outside of the inner circle of the "usual suspects," metaverse was a pretty esoteric term before 2021 (as this Google Trends proves). So how has a dystopian novel turned into a trillion-dollar industry almost overnight?
