I do games research for a living and have access to pretty much every relevant VR headset made since the first Oculus.
VR is very much a gimmick. There is no killer app or feature, and the closest thing we get to one are exergames like Beat Saber. Games like HL: Alyx don’t really offer enough novelty to make people invest several thousand dollars. Similarly, virtual desktops are neat but really don’t offer any tangible benefits compared to a large monitor to make up for the added discomfort of having to wear a VR headset. The Snow Crash-style metaverse is and always has been absolute bullshit. It’s just a less convenient version of the metaverse we already have.
VR has some potential to create cool embodied experiences, but the benefits so far are so slight that the technology is looking a lot like 3D TV and HD-DVD: technically impressive, no meaningful improvement in the holistic user experience. Hence, it remains a gimmick.
