The author "invented the metaverse" because they ported a text based game to one with terrible visuals that was never really sold or used? It's a strange kind of inventor that never implements his invention or describes it so well that it might be implemented. If I have an idea for a humanoid servant created from forcefields and holograms and create a mockup with a mannequin and a bucket - I shouldn't be able to call myself the inventor of the holographic-assistant. Further, if that technology ever became slightly plausible I don't think I'd have any special insight because I spent a bit of time doing something that obviously didn't work decades ago. The hard part about the metaverse isn't thinking up the concepts. That's been done already, multiple ways by many people. The hard part is turning a fictional idea into a reality.
