Page 49-50: Crystals of imagination:
Consider two types of apples: those that grow on trees and you buy at the supermarket, and those that are designed in Silicon Valley. Both are traded in the economy, and both embody information, whether in biological cells or silicon chips. The main difference between them is not thein number of parts or their ability to perform functions—edible apples are the results of tens of thousands of genes that perform sophisticated biochemical functions. The main difference between apples and Apples is that the apples we eat existed first in the world and then in our heads, while the Apples we use to check our email existed first in someone's head and then in the world. Both of these apples are products and embody information, but only one of them —the silicon Apple —is a crystal of imagination.
