Who cares because we will all be dead by then.
To really answer the question, first you would have to define what is a "video game". For instance, if by "holograms" you mean some kind of 3D game in space, I would still consider it as a video game, just as I consider VR headset games to be video games. Just more advanced video games as what we have today, as far as display technology goes.
I don't see the need for people to have some digital entertainment and (even competitive) games going anywhere. The technology used for it may change, but who cares? As long as the holograms and matrix virtual reality are fully DRM-free, I don't care.
Canuck_Cat: It's already happening right now for some people. Video games still exist, but their tastes and priorities change to other hobbies. For example, reading, outdoor activities, board games, exercise, streaming TV/movies, tourism, etc.
LUL what? As far as I can tell, the direction has been exactly the opposite, for years or even decades.
More and more people, even common non-hardcore gamer people, have moved from those other activities, more and more to spending their times with "video games", or social media. Including from watching movies or TV.
Right now there may be a slight wave back, as people are going out more and more "after" COVID epidemic.
