The Core

They were making windowless buildings in the 1950s, especially schools.  My wife's HS had no windows, the idea was that the kids would pay more attention to what is going on in class if they didn't have nature as a distraction.  I personally hope this doesn't become a thing, I like being distracted by the outside world.  I ride BART (SF subway) and it really is an unpleasant experience, everyone on there seems to be miserable being part of a mechanized process.

it instead has cameras recreating the visual effect of looking out, and much more continuously and impressively than is possible when you are relying on real windows.

No holes in walls, no glass, cheaper, better view.  And no blinds, NFFC. Just flip a switch.

though tech is cheap enough now to have a real view in a fake window. see jet above.

And we haven't even broached the idea of window hybrids using varying degrees of AR.  So, assume that emulated windows take off due to low cost of ownership. (They will, high cost construction first. Recording studio designers have been working on fake windows for a while now for soundproofing, but only recently have technologies become cheap enough for it to be viable, imo.)

Can't quite see the ocean from your condo? Easy fix if you can manage a better camera location.  Don't like that power pole in the middle of your view?  Have your $5 RPi snip it from the rendering on-the-fly.
