You have as much computing power in your iPhone as was available at the time of the Apollo missions. But what is it being used for? It’s being used to throw angry birds at pigs; it’s being used to send pictures of your cat to people halfway around the world; it’s being used to check in as the virtual mayor of a virtual nowhere while you’re riding a subway from the nineteenth century.
