Incidentally, much as I love this image and the associated animation, I disagree with this concept of future cities. I suspect that technologies not yet existing will put an end to the need to concentrate people and buildings and machines this way. Indeed such a city may be abandoned because it's uninhabitable, and people may disperse and live much as they did a couple of centuries ago, except that they will have computers, microwaves, electric cars etc.
This is an interesting point of view and you're probably right, but I think that regardless of the real needs of people, there will always be big huge, useless and polluted cities. In my opinion, insanely huge cities with crazy architecture has always been mankind's way to show to the rest of the world its power and balls, whether it's in great contries of freedom and justice or poor dictatorships. (Manhattan, London's new architectural projects, Hong kong, Dubai, Astana in Kazakhstan, etc..). Man's eccentricity will unfortunatelly keep leading the way of how major cities will be shaped tomorrow, the surroundings will probably be wiser. But this is only my opinion.
You may well be right. Cities outside the US seem to be building taller and taller, for no good economic reason, but just in imitation of what we were doing decades ago, and as an exercise in penile supremacy...
Like a picture of an actual futuristic city! The blur effects on the ship to the top left corner, the subtle glows of the neon signs and the various room lights on the building are dispersed in a random pattern.
But this is only my opinion.
