It just means fast loading assets, so if SSD becomes RAM one day, anything interesting at all? Same goes for ray tracing, looking more realistic with control of light...

Nothing special here, no need to hype

edit:

You know what really makes a difference?

You playing an VR open world game where every single artificial intelligence NPC does thing in every possible way leading to different gameplay and outcome. And you as a character can just grab anything you want and throw at any monster that you just CREATED in that game itself

Or you can control that monster that you created in your own way, time travelling to another open world game saying hello to your friend playing in his house back and forth

Together with some AI NPC friends you made in that game, you live in that dimensional space forever as you want even after your human body dies, your conscious stays in electronic form
