I don't think the possibility for beauty can be foreclosed, because beauty can take so many forms. There is beauty that arises from the unexpected, when our familiar perspectives are thrown off balance. There is also the beauty that paradoxically comes out of the tragic, that emerges because we are reminded of what is no longer there, that becomes powerful because of what is absent.
Every time I would arrive in China I would go through a few days of depression from being reminded of both short-term and long-term ruin; the ruining of the city that is happening in the short-term, and the ruining of culture and history that has happened over decades. When you see a building that says so much about the culture that built it being destroyed, there are a lot of emotions. You feel a lot of anger when you see a building being destroyed and realize that it's just a small part of what's going on in the entire country.
The paradox in China is that while some things change very rapidly, others don't. The appearance of its cities may be entirely different, but the inner workings behind these changes still persist: the regulation of society, the hierarchies of power, the relationship of the individual to the majority.
