This will definitely be on my 'bucket list' of places to see. It is way cool, IMO. It is another reason to see China.

Is this just another mammoth Chinese development built for the sake of GDP that will stay empty?

This looks like (and sounds like) a glorious realization of a sentiment promoted by corporate interests in America and China (and perhaps Europe). If this has actually been made to work, I hope its momentary success can be enjoyed by folks whose experience of exploitation makes them deserving of an earthly heaven (and who can blind themselves to the punitive environment which is inevitably developing outside). I cannot deny the sense of horror which grew in me as I watched its promotion. Have its corporate developers no sense of guilt?

Maybe but not likely pin. It's a classic "if you build it, they will come". It has so many reasons for people to want to be there, for both the local population as well as international visitors. Its MASSIVE scale is mind-boggling, and i would like to see it covered live instead of this animated video promo. Every little detail seems to have been thought of. It illustrates the epic capabilities of today's Chinese culture. Truly remarkable stuff, but for its success, the jury is still out.
One has to admire this (and other) expressions of modern China, especially if you consider the population density compared to the west. And for those who think in the chauvinist American/Hollywood style of "we do it better", it may not mean very much.

Look up Ghost Cities in China this is just another of china's ridiculous GDP growth projects that rarely pay off. Art requires Freedom you are not going to find it in China.

Sorry no. The Boeing Commercial Aircraft plant in Everett WA is still king.

My office will be there as of next month and I can accurately say that it's an awesome building. One must do research on Chengdu to fully understand why this building and it's location makes perfect sense.
My lunch breaks are going to be rather nice....

Largest building, fastest trains, most college graduates, soon-to-be-biggest economy... We're falling behind fast folks. Our world dominance will soon be a thing of the past. Get used to it!

Did they actually describe their road infrastructure as 'omnipresent'? Twice? Leave the omni descriptions to God, thank you very much!
At 13:40, did they actually use 'pompous' as a complimentary adjective? Wow! Can anyone say self-aggrandizement? While giving them props on the accommodations, I must say they have to work on the humility component, or lack thereof!

"Our world dominance will soon be a thing of the past."
US global domination was a fluke for which we must thank Hitler and Churchill. It was inevitable that such dominance is fleeting.
