I think facebook will not create their own Meta world, they are just going to build their own existence into a meta between their companies and that is what they will focus on. I do believe that "ready player one" could be the future, maybe not offline world, we will keep offline world a bit different to be fair, but the online world could reach those levels in the future and we have the tech for it.

In fact, if we spent enough money with enough talented people, that is quite possible even today, but would require insane amount of money and workers and time, which would result with not profiting, so people are not focusing on that right now. If we are having trouble with cyberpunk, imagine problems in a game like that. We will get there, it is just going to take some time, we might get old by then .
