I don't really know what's going to happen 10,000 years from now. We've been biologically modern for, what, almost 200,000 years? Let's go back to the cave paintings: I think the moment that someone landed a charcoal on a wall to describe reality, that's language already - that happened on a vertical surface, which, even though they didn't build it, somehow we could understand it as architecture because there's a cavity that separates the inside and outside. That's 40,000 years in the past.
