Universalism or varied identity?

First off, HAPPY NEW YEAR! hahaha, I know, it's sad that only 2 days into 2010 I'm already here. =P

I can't quite get it, but it seems to me, that the world has obviously picked one side compared to the other, and thats varied-identity over universalism when it comes to architecture. I suppose at the top of my head it's because every building is built by a different architect, and even if it were the same guy, that architect is trying something new each time AS opposed to a world of robots n tasteless buildings. PLUS they're all constructed in a different time, hence fad; AND the funny clients tend to be a big influence (or disturbance =P)

UNIVERSALISM

how can a city have so many buildings... almost everyone using a different strategy compared to each other: material or whatever, why do they all differ so much when some obviously work n some dont. Why doesnt everyone just follow the same one way? I wonder how much they value this identity thing that it compromises the workability of it. Now I'm not saying everything has to come planned with the same entrance same system etc. Just the same solution (unless there comes a better one which revolutionises the city) I have a feeling some being be thinking of this...left: LeCorb's vision for Paris

Haha, but seriously, that's not what I'm saying. Doesn't it make sense that if there is already a better solution, that we should all use it? At least as a base outline of the building , all of them should be responding to the same site right? Shouldn't they all look SOMEWHAT the same? Of those who oppose, what do you think then of this? right: Zira island by BIG

VARIED IDENTITY

I honestly do love the way most cities are built so far, cityscapes tend to look beautiful at night in every country. Left: City of Seattle Sometimes, topped with an icon, among the similar buildings this identity uniqueness work very well, but what if everyone had the same impact of uniqueness? Right: Ansan masterplan by various architects I personally thought this looked alil messy. In this scenario, assuming each great architect made their building perfectly responsive to whatever their criteria needed, could the same law not be applied into a city and have a zoo? Do each of those singular buildings behind the SpaceNeedle not deserve to look crazily unique?

I suppose this post changes nothing at all, because overall, there are so many reasons affecting the outcome of one building design (cost, client, time, function, surrounding, vista, occupancy, trend, concept, etc etc) that there's no way a city could have every building using the same solution unless there was a law to it. Where it still always comes down to the governors, politicians, presidents, men in power. Sigh, I wonder how they try to cope with everything in such detail.

p.s. I guess what I'm fighting for is another "international style" to move over the globe that appears to 'solve all our miseries' until we move on to new problems agaim. Could it be Parametricism?! =P
