You don't need to upgrade anything. VR/AR are their own computers. They require no external dependence.
It's pretty clear that VR/AR in the home will have tremendous implications for usecases such as communication, virtual offices, virtual schools, exercise, art and performance, lifestyle, travel, live events, and entertainment / media.
Not all VR/AR devices are their own computers. Being their own computer though, I doubt they will always be stand alone. The Apple Watch isn’t even stand alone when it can be. There will be some kind of eco-system feature that will require users to sync between other devices for maximum features.
In fact if they are tethered to a device that brings the costs right down to an affordable level. AR glasses that do all the compute on the phone will mean the glasses can be lightweight and don’t need a large battery.
Yeah I can magically imagine these being used to improve every sector in the universe. Imagining is easy. I can imagine self walking 3D printed legs that take me to work, but people will laugh at it.
Magically imagining things is different from making them work.
You already have a school with a tight budget. Now you add the VR thing on top and what? You need the extra budget to develop and maintain on top. But what is the benefit? Did it fix anything? Can students study better with an expensive headset? Doubt it.
Exercise? People magically become stronger and fitter because VR on top of the exercise? The exercises already work. A dumbbell curl without VR is the same dumbbell curl with VR. Adding something on top is just an extra cost.
Travel? OK virtual travel. I can already watch travel videos. Why do I need travel videos in 3D? There are privacy implications with that and high maintenance costs for whoever develops that. They have to get permissions from locals for so many reasons.
Virtual office. This one needs a new compatible computer tethered if it is using desktop apps. But why virtual office? Outside Mark Zuckerberg’s stupid presentations that everyone laughed at I don’t know what’s the point. Just use chat or FaceTime/Zoom, etc. Which brings us to…
Communication? We already have video, audio, 3D communication. Why do I need something on my head that costs so much? It doesn’t add anything. You are asking for everyone in your circle to have the same device. What if half of them don’t because it doesn’t add anything of value?
In every case, there is a big cost on top of what already exists. It’s not just a hardware cost.
If you ask me only 1-2% of people will have it and most of them will be just watching adult content and dying of loneliness.
