I think there will be two distinct tracks for the future. One will serve the masses, in particular developing nations, and that is, the factory built box (or boxes) which by then will have shed the current trappings of historical references and come preloaded with all the technology imagined in the previous posts. These will be built in dense urban settings, both highrise and low rise. The second track will be a backlash to the first: a return to handmade traditional houses of high qualitity, built in more natural settings, with very little technology, and a greater relationship to the land. These will be for the "1 percenters" or maybe by then it will be the "10 percenters", globally speaking.
This is all just my offhand thought- not based at all on any data. I think it suggests the possibility of a reversal of what we have today, where the middle and lower middle classes are more interconnected by technology and the upper echelon is increasingly isolalated.
