All discussions that deal with the metaverse, both positively and critically, ultimately exhibit a significant weakness that manifests in two different forms. On the one hand, the discussions remain superficial and fundamentally vague because the metaverse is viewed as an all-encompassing and thus unmanageable large future construct. On the other hand, many discussions are based on isolated examinations of small and very small niches and use cases that are not placed in any overarching context. Both perspectives share the same weakness, namely that it is ultimately never exactly known what the metaverse will be, or more specifically: how the metaverse will be technically and functionally structured. Nevertheless, both established national and international organizations and renowned experts from various disciplines attempt to identify potential applications and use cases.
