Ted Chiang is an incredible storyteller. I only read two of these stories (the ones nominated for Hugo, "Omphalos" & "Anxiety is the Dizziness of Freedom," so I still get more from this one. For now, though, I loved "Anxiety" so much. I love the concept of the prisms, especially their limitations and the resulting economy. Chiang created a very strange world, quite haunting, haunted by need and greed. I loved the story.
