The OP was wondering about how these could be used.. as if there was no obvious use cases. I shared only a few possibilities. Whether the potential for this is towards heaven or hell is TBD… and at least somewhat eyes- and ears- of the beholder.
There is a respected physics theory that wonders if all of our current reality is a hologram. If so and through your interpretation, we are all already in THAT prison.
Sorry that this concerns you. It’s coming anyway. Embrace it or not. “Resistance is futile.”😉
You should not take that “respected” physics theory literally.
When we talk about these headsets we have to talk about the user experience. Science fiction fantasies don’t apply here. People are physical, we feel pain and discomfort. The older we are the worse it is. We get impaired vision, rusty necks, wonky spines, painful joints. We cannot be asked to move our heads and bodies with a computing device for a lifetime.
That has been the experience of Oculus users through every generation of their headsets. They buy it out of curiosity but then find the device to physically and cognitively demanding to use for longer than short bursts.
There are many problems that are simple impossible to overcome if you want an ‘all day’ head set, and even Tim Cook has said he doesn’t see this device as being used for long periods.
Those problems range from battery life, processing power, operating system bugs, graphics performance bugs, throttling processors, intermittent failed wireless connections, etc.
All these problems are present in Macs after decades of development, in iOS after 15 years of development, and will be in xrOS. But in a headset these problems are completely unforgiving. There’s no room for error otherwise the user feels extreme discomfort, disorientation and distress. It’s one of the reasons so many Oculus devices are left to collect dust and why Horizon Worlds has poor user retention rates.
This will always be niche. Trying to make it the ‘main’ way of computing is a bad idea and anyone who wastes energy, time and money trying to argue that it will displace desktop and laptop computing will have egg on their face. When they are older and wiser they will look back and wonder what the hell they were thinking.
