Maybe it's just me and my enthusiasm for this project... but honestly, I really don't get what the naysayers "don't get" about this building's size, it's purpose and it's location.
This building isn't meant to be any old mixed-use skyscraper in some typically skyscraper dense urban city...
This megastructure IS the City!!
Inside will be all the things you would want to find in city of 30,000 or so residents... businesses, retail shops and grocery stores; hospitals and clinics; arts and entertainment; green spaces, parks and gardens; schools and higher learning centers... etc, etc, etc.... AND the homes of those 30,000 or so residents!
Most likely the small community surrounding it will continue to thrive and probably see growth as it becomes the support structure for the Sky City that will become it's core.
I really believe we have to broaden our perspective about what this building really is. It's not just a skyscraper... it's not even just a supertall. This is a whole new concept in how and where people live, work, play, and exist. And even if it's not a "new concept" (Tokyo's Sky City 1000?)... it is certainly and now undeniable the first attempt to realize such a grand experiment.
Let it stand alone in a field. It's supposed to! Embrace the idea of the world's first self contained city-in-a-building... and just let it be what it's supposed to be.
