VR is still a niche, but I wonder if the transition from tethered VR to cheap and easy to setup mobile VR (not cardboard) will finally make VR mainstream.
I think mobile phones may not be powerful enough to be used for VR and if they are probably too expensive for most of the people to buy.
You are mistaken. Oculus/Facebook is betting heavily on mobile VR with their latest entry level and mid level headsets, the Oculus Go released earlier this year and the Oculus Quest in a few months. Mobile VR is not a theory. It is already here.
Saying this would make ur grandfarter turn in his grave. 50 years back no one dared to think about cumbersome stuff like this which only pollutes human brain through constant discharge of radio waves of short wavelength which is to traumatize ur sore sensory organs and receptors even more. Wear a bowl with liquid boiling lard on ur head to amplify ur perception of virtual surrealism. Fucking nuts.
