I live in Melbourne, Australia, and we have some of the worst and best. Some of our new apartment buildings are atrocious examples of developer greed.
But some are enhancements to our city, and there are public and business buildings that are similar, while still advancing both technology and architecture.
A lot of the criticisms in this article aren't about architecture, but about town planning. Mixed-use neighborhoods and human scale development is not just individual buildings, it's how they inter-relate and work together. It's about transport systems and infrastructure as well.
The appeal of Gaudi and others is that their architecture is organic and there's no reason modern architecture and infrastructure, especially as we green our cities, won't evolve in that direction.
