Probably worth of value to ask some side questions:

What is the future of writing?

What is the future of art?

What is the future of pictures, videos, etc?

That said, I think the key thing for games is that it is a way for humans to connect with other humans. Imagine a world with teleporters. Would you ever want to play chess with someone else over VR when you could just play chess with that person in real life? The other thing is that different media formats allow for different experiences which are fun in and off themselves. A lot of the best video gaming is only possible through different technologies rather than just copying stuff that was great in other formats.
