  Assuming that the term 'metaverse' could be understood as a computer-based
implementation of multiverse applications, we started to look in the present
work for a logic that would be powerful enough to handle the situations arising
both in the real and in the fictional underlying application domains. Realizing
that first-order logic fails to account for the unstable behavior of even the
most simpleminded information system domains, we resorted to non-conventional
extensions, in an attempt to sketch a minimal composite logic strategy. The
discussion was kept at a rather informal level, always trying to convey the
intuition behind the theoretical notions in natural language terms, and
appealing to an AI agent, namely ChatGPT, in the hope that algorithmic and
common-sense approaches can be usefully combined.
