The metaverse concept is that of a large-scale social environment based on the convergence of virtual and physical reality. Participants can take part in the metaverse through virtual, augmented or mixed reality. They can carry out everyday activities together, ranging from entertainment through to education, business, politics, health or even legal proceedings. At this time the metaverse is more of an idea than a reality, but a number of nascent systems exist, and all the technological components, including solutions involving AI, are available to bring this idea into existence.
