This document discusses the implications of digital identities and learning in virtual worlds and future metaverses. It notes that over 700 educational institutions currently use Second Life for digital learning. Studies show that virtual world simulations can be as or more effective than traditional classrooms, as seen in Loyalist College's border security training simulation in Second Life. Virtual worlds allow for geographically dispersed students and faculty to collaborate synchronously from different locations. However, concerns about cyberdisinhibition effects and potential addiction are also discussed.
