Interesting article, and nice work! For those who are interested I wrote a book on Social VR and basically how to build your own Open Metaverse. Which I'm pretty sure will run on both platworms Meta and Apple as long as they both keep following the W3C WebXR specification. Which is kind of manditory if you what to claim you are a metaverse compliant technology platform. Anyway, here is my stuff, book, blog, open metaverse examples and actual working server. The culmination of over 15 years of work given away for free! Hack the Metaverse! Hack the Metaverse! Open Metaverse that is... spead the word. https://rocketvirtual.com/
