What is Metaverse?
Quick answer
A loosely defined vision of persistent, shared virtual worlds where people interact, work, play, and trade using avatars.
Metaverse, explained
The word metaverse comes from Neal Stephenson's 1992 science fiction novel Snow Crash. In recent years, technology companies have used it to describe immersive digital spaces accessed through virtual reality headsets, augmented reality glasses, or ordinary screens.
Existing examples include large online game worlds where users attend virtual concerts, social VR platforms, and virtual offices for remote teams. Some visions include digital ownership of items through blockchain tokens. The concept attracted heavy investment and hype around 2021 and 2022, followed by more skepticism as user adoption grew slower than predicted. Open questions include interoperability between platforms, hardware comfort and cost, privacy, moderation, and whether people want to spend significant time in such spaces.
