While it is true that concrete and steel cost resources as well, in a resource constrained world, we will use what we already have in place as these things are quite durable. I don't envision a future of mega skyscrapers and bullet trains, nor do I envision a world of Oculus clad employees driving a virtual forklift. Rather I view the world continuing to exist as we currently have it: forklift driver is prompted by his UI to go to the next location to physically grab an item.
