I just haven't seen any real signs that gaming would fade out at this time. Even with the advent of VRs, non-VR gaming is still relevant and has a big market. Consoles are still selling well despite the PS5's struggle with exclusive games. The PC hasn't really changed much from the 2000s aside from better graphics (longer than that if you count MS DOS as a "PC"), and I have a feeling it's going to be the longest survivor if gaming does become dated in the future, especially with how much we use the PC for a variety of activities besides gaming.
I do see VRs as the big thing in the future though, but as much hype as I'm hearing about it, I'm just personally unimpressed by the tech. It feels like one of those technology where it feels like sci-fi, but still feels pretty grounded and contemporary in the same way cars still feel grounded and contemporary (unlike the flying cars of sci-fi films). Until I see something truly groundbreaking and revolutionary like holodecks (where I can literally smell the flowers and touch the grass in a game), I just don't feel the "technological change" in the industry yet from my gaming experience in the 2000s/2010s.
As for whether gaming itself will become irrelevant regardless of the VRs' existence... unlikely. People will always need a hobby and something to kill time, going as far back as the cave-drawings of the Stone Age. We've just become more advanced in our leisure time beyond painting in caves. I haven't really seen the next big thing in leisure yet, unless you want to count the problematic Metaverse, so I think gaming will still be around for at least... optimistically speaking, the next 50 years.
100 years is a more challenging gauge to measure though. I'll grant you that, at the very least, over the last two decades, how we live as a society has changed a lot, so who knows with the following century. And in the past century, technology has definitely improved exponentially. To quote a deleted scene from the movie, Prometheus, "20th Century: the automobile, television, nuclear weapons, spacecrafts, Internet. 21st Century: biotech, nanotech, fusion and fission and M-theory - and that was just the first decade." So yeah, technology has advanced on a far more incremental pace than ever, so who knows with the next century?
But I still stand by my stance that gaming inherently wouldn't really go out of style, nor will people's need for leisure disappear. Perhaps we might see a new form of gaming in the future. Well, I wouldn't see because I'd be dead. Our children would, but I wouldn't know. lol
