Why would I want to strap a clunky VR device to my head to enter a 3D VR to then awkwardly use a virtual keyboard to type an email? Why would I want to do a 3D VR call with low-polygon avatars when I can just do a regular video call? There are very few use cases where this adds anything. Even in gaming, it will probably remain a niche genre, because most genres just work better without VR, especially competitive ones where input precision and latency are crucial.
