The word metaverse comes from a 1992 novel called "Snow Crash" by best selling author Neal Stephenson.  It's characters interact with each as avatars - or online personas - in a 3D virtual world with its own economy.  Today's real metaverse combines VR (virtial reality) headsets with the latest in gaming and social media...as well as cryptocurrencies, NFT's (non-fungible tokens) and other decentralized blockchain apps.           Make no mistake...the Metaverse is on the cusp of going mainstream.  The Metaverse will build on and transform todays Internet.                         Facebook is creating a virtual world called "HORIZON."  FB has already debuted an App for adults called Horizon Workrooms.
