Cloud based live rendering

With the microsoft hololens and magics leaps glasses leading the race to a deviceless futur, In the next 15 years, hell ten years we might live in a futur where where virtual and physical worlds are visually existing in the same space. For those " hologram to reach a level of unprecedented realism I see those company take the computational power out of the equation for the hardware, greatly reducing the size of the device and giving the ability to leverage the 5G or 6G network to offer what I call a cloud based live renderer, imagine having the equivalent of multiple top grades and processors giving making movie grade cgi on the fly, able to do live ray traced, physics simulation based of the constantly moving environment. Can you imagine the possibilities of such a future, then we add to that a machine brain interface oflike envisioned by Musk and boom you have simultaneously one the most awesome and most horrible futur imaginable.
