ElevenVR has, according to themselves, 1 million players (https://elevenvr.com/en/), how many active I don't know. That's just one niche. Other popular games/experiences are various shooters (Onward, Pavlov etc), rhythm games, fitness games, social experiences like Rec Room and VR Chat, movie/tv viewing apps, golf. Fitness has to be the most surprising one which few people would have predicted. For me, a few of my friends bought one together so we can hang out and play games, as we live far away with families these days. Remote meetings is obviously a huge potential one, but we probably need one or two hardware iterations to make that a compelling alternative to video. So it's safe to say VR has found some compelling use-cases, the question is if it's enough to sustain growth. More use cases will open up as the hardware gets better, so I think so.
