As someone who's spent a large amount of time in Beat Saber I think half the problem is that as good as VR headsets have gotten since the introduction of the original Rift, they're still full of compromises. None of them do everything well, and so you have to pick the one that sucks the least for a single use case (fitness games, racing/flight sims, VRChat, etc), and that's really bad for something as expensive as VR headsets are (even the cheaper quests). In the case of Quest stuff, PC link users being treated somewhat as second class (no direct DisplayPort input) and the lock-in of the crappy Quest desktop software doesn't help matters. I agree that VR will always be a niche, but I would also say that there's a good chance of the niche growing with the introduction of a well-built, affordable, well rounded headset that's built on the SteamVR ecosystem.
