To hear it from Meta CEO Mark Zuckerberg, in just a few years the entire world will be able to step inside a virtual-reality utopia where they can live their best lives. Remote work meetings that put everyone in the same room, immersive rendezvous with far-flung friends, raves, shopping sprees, card games that for some reason involve a space robot—all of this is supposed to be possible in the metaverse, the concept of a shared, virtual world that Facebook so wants to dominate that it gave itself a new name.
