Do you like this building?

I came across this ad in the New York Times magazine. I should say, I was riveted by this ad. Is this a real building? Is it built yet? You have to take a look at some of the images on (what I think is) their main site.

But really the ad in the magazine is the one that is still the most impressive.

Which leaves me with the question, is this thing a good idea? I wonder?

Just quickly looking around some of the stuff I read online about it leaves me with the question of whether this is an architectural/engineering/construction tour the force which in the end will not much improve the world.
