Wow. Mesermizing.
When we went to China in... 2002??... we had a hotel room right across from a construction project that looked like this - about a dozen high-rise buildings going up at once, with one of them half inhabited and the furthest behind being a skeleton structure. I think they were all 16 stories. I sort of wondered about the wisdom of building them all at once instead of getting one up and rented/sold, but didn't think much further than that. It never occurred to me that the project would stall and a decade later, they would all be destroyed.
Such a waste of resources. That's a lot of concrete and steel.
