PCVR capabilities are too high for it to be a dead end. More niche, absolutely, because mobile VR/AR has somewhere from console to smartphone-level growth potential--but a smaller, higher-paying market for premium experiences is going to continue.
Absolutely agree with this, literally anyone who can use the headset is able to sculpt a 3D model in Oculus Medium that resembles what they want. Same can't be said for any non-vr 3D modelling software, huge potential in the creative industries.
Still niche and not mainstream though.
