Earthscrapers: we may be living underground a few decades from now ...
we don't miss the sun now A quarter of Americans

Oddly enough by using proper design earth scrapers can be built to have sunshine inside.
It's already been done...
Chinese five-star hotel is being built INSIDE a quarry 100 yards beneath ground level
Rock Quarries are rather common...like near DownTown Chicago
I must have crossed that bridge a hundred times.
But RockQuarries are so last year think BIG!.
Why not put a city in an open pit copper mine?
