Is that true? From this article[1], it sounds like he had been pushing for cheap headsets, not expensive ones:
> There he talked about his internal efforts to push for the development of a "super cheap, super lightweight" Meta VR headset that could come in at "$250 and 250 grams." Instead, Meta has put its recent VR hardware efforts behind the heavily overdesigned and expensive $1,500 Quest Pro. "We're not building that [cheap, light] headset today, but I keep trying," Carmack said with some exasperation during the keynote.
