Right now the value of real estate varies tremendously with whether or not it has a good view. Alas, no matter how much money you pay, you always get the same view.
At some point, when extended reality specs become as numerous as smartphones are today, that will change. You will be able to decide what view out of your window that you want on any given day, whether of The Eiffel Tower, or of the Grand Canyon, or of a lunar landscape.
I wonder what that will do to the value of real estate.
