VRML is a relic from the 90s. Complaining that nobody wants to use it now for modern VR is like complaining that Netflix doesn't use MPEG1. Netflix is just having fun reinventing video compression!
And the reason VRML even exists is that somebody just wanted to have fun reinventing 3D graphics in the 90's, so it doesn't deserve to be used just for the sake of not reinventing the wheel. It's an old shitty wheel that was a reinvention of another invention(*), done just to be fun to implement, but not fun to use.
(*) It's funny because it's true that VRML is literally a reinvention of Inventor, and Open Inventor is a reinvention of VRML.
I wasn't saying that everything invented in the 90s is now a relic. Lots of technology from then has stood the test of time and is still useful. But VRML is not one of them! It wasn't any good even at the time.
