What's different is that Meta has sold 20+ million headsets, and there is a decent sized user base, albeit much smaller than people expected 5 years ago. This is not a dead technology just because you don't use it. In 2023 Meta Quest had roughly 6.3 million monthly active users.
So, in some sense not a lot, but it has a decent foothold of people using it often. It's clearly different from VR in the past where there were literally a handful or maybe on the order of hundreds of headsets in the world. VR now also has a ton of different niches and use cases beyond games. I also think a comparison with gaming console hardware is more apt than comparing it to something like PC or smartphone sales.
According to this, 1.63% of Steam MAU have a VR headset which translates to roughly 2 million MAU: https://store.steampowered.com/hwsurvey/Steam-Hardware-Softw...
