There's very little novelty in what VR provides - it just provides a significant enhancement in the experience
Also, limitations can breed efficiency - by being constrained to a 2D projection, the interactions are simplified and streamlined
VR provides the same goals and expects utility (fun, efficiency) from the process.
Its fun and interesting, but I haven't seen anything groundbreaking.
Frankly, I think VR and FB are a good match for another reason - they both provide an overwhelming, dissociating experience
This can be a boon, but like sugar and opiates I worry that they're more social or sensory information than we can take in chronically - unfortunately, huge amounts of money and thought and technology is aimed at maximizing our intake to pad coffers.
I'm not sad AR/VR adoption is lacklustre
