Interaction feels like the issue with headsets. You either need a fair bit of space for gesture controls, or you have to talk to yourself for voice control.
I think VR has more niche uses than the craze implied. It’s got some cool games, virtual screens for a desktop could be cool someday, but I don’t see a near future where they replace phones.
The risk/reward tradeoff of helmets is potentially dying, and we still had to make laws requiring people to wear them.
Glasses also have a pretty compelling reason to wear them.
I don't think VR has as compelling of a reason, at least so far. Even if it does, you need people to get far enough in to see that reason which is a hurdle when it involves a device they don't want to wear.
