No I doubt it. Why does everyone forget about the “game” portion of the metaverse? You can’t just build it and expect people to join if the underlying game isnt fun. If it’s just some digital hangout spot then that’s boring sorry - been done before and most people don’t care about virtual chat rooms.
I don’t think FB knows how to make games. They know how to make social media platforms and web technologies but making games is it’s own skillset.
