Carmack never made interesting worlds, settings or themes. That was done by others. His brilliance came from making tech and tools that could bring those worlds to life in an era when the tech seemed impossible. Yet VR is just so much harder, no one person alone can really polish to the level needed for mass market adoption. Heck even Doom (1993) era tech still makes a significant part of the population sick.
