XR in world model

I mean the virtual model of world instead on cloud, can be mixed reality model, and people can see things as common as every, augmented, and vitual stuff can be interacted as common for all, served by server, projected , seen from digital eyes of VR XR say in metaquest, generate a scne which shows such augmented virtual reality

so objects in virtual spaces which are public in world model can be seen by anyone, on a common server, enabling extended interaction in physical world
