I was just about to post the same thing. I’ve been using Linux for almost 10 years. I never really understood the folder layout anyway into this detail. My reasoning always was that /lib was more system-wide and /usr/lib was for stuff installed for me only. That never made sense though, since there is only one /usr and not one for every user. But I never really thought further, I just let it be.
I use it for sim racing sometimes and it’s amazing to feel like I’m in an F1 car or something. Until I get nauseous after 15 minutes or something. It’s also a bit of a hassle to set up. That being said, maybe it would be cooler if I got into beat saber or something.
Was it over hyped? Maybe. But it’s still a cool technology and I’d be sad to see it fall into nothingness. I don’t see a future where everyone is wearing VR glasses, but it’s still a very neat thing to enjoy every now and then.
