Not "no" Culture. Think of Culture as having two parts, the inner and outer. The inner is the ideas that make it what it is, the outer is the expression of those ideas. So we (I assume you're a Westerner) Westerners have for a very long time had ideas about what is beautiful, what is good, what our purpose is, etc. We express those ideas in our art, our architecture, our music, etc. Both of these together form a distinct Culture.
Now, imagine that the ideas which made our Culture the Western Culture stopped being universally accepted as true. The art, the architecture, the music, all of it would be preserved in our history. And, people would still make art, architecture, music, etc. But the unifying ideas which made the Culture Western have been taken away. The outer is still present, but the inner is gone. The new inner is just relativism, content without any unity. Therefore, the outer has become arbitrary, to reflect the inner.
This is the situation we are in, or going through now. Because art, architecture, music, has all become an arbitrary expression of an arbitrary inner reality, people turn to more practical endeavors in general. Eventually, the distinctly Western Culture will become an oddity of the past, commoditized and sold, since its monetary value will be its only value. And, eventually, the Culture as a whole, not just it's artifacts, but its people, will stop being a unified One, and simply become a mass of people spread across arbitrary national boundaries and geographic impasses.
Then some new unifying force will come along, and the cycle will begin anew.
