>>1760346never, the era of the skyscraper is over
it was bastardized anyway, initially it was to solve genuine lack of space in manhattan (though moving people out of manhattan would've worked too), but eventually it became a race of unending vanity, and after arabs out-vanity'd everyone with their kilometer tall needle that's so tall you can get altitude sickness if you rise from the bottom too quickly and their plastic fairlyland hotel for mekka piligrimage everyone became disillusioned and decided that skyscrapers are indeed useless
look at japan, despite actual scarcity of inhabitable lowland space, their big metropolises are all low-mid rise, tokyo tower is shorter than empire state and it sticks out of the rest of skyline quite a lot
