You are right about the complexity but other fields seem to have progressed farther in their software. You hear of Catia and the software for Aerospace. I guess this is almost as complex as a building. I think our fees are so low that they know they could not recoup the expense of software development.
Or maybe it will just be a matter of thinking different about describing a building for construction and what it should entail with new 3d display methods. Think of cheap iPads on the construction site and the large screen in the construction trailer. By the way I hear Catia is creating Live Buildings software.
