Every five years or so, VR gets to be the next hot thing. My first VR ride was on SGI Indigo, so it's been a while. Believers say we're almost there; I beg to be skeptical at this point.
When we can use AI to generate entire environments out of our favorite shows and then we can walk around in them and do stuff, then it will be here.
The tech to do that exists in its infancy at the moment but the compute required to execute it makes it unfeasable.
The hardware is here and the games are here, just because there isn’t something that YOU want doesn’t mean it’s not a mature technology.
I also played a military SIM a few years later on a SGI O2 but it was really stupid, no immersive controls etc.
