Tyler Cowen on the iPhone

Like many others, I’ve been reflecting on the tenth anniversary of the iPhone. The Computer History Museum ran a fascinating two-hour show in which John Markoff talked to some of the people who designed and built the first phone. Tyler Cowen also devoted his latest Bloomberg column to it and, as usual, he’s come up with an angle that I hadn’t thought about much:

First, we’ve learned that, even in this age of bits and bytes, materials innovation still matters. The iPhone is behind the scenes a triumph of mining science, with a wide variety of raw materials and about 34 billion kilograms (75 billion pounds) of mined rock as an input to date, as discussed by Brian Merchant in his new and excellent book “The One Device: The Secret History of the iPhone”. A single iPhone has behind it the production of 34 kilos of gold ore, with 20.5 grams (0.72 ounces) of cyanide used to extract the most valuable parts of the gold.

Especially impressive as a material is the smooth touch-screen, and the user’s ability to make things happen by sliding, swiping, zooming and pinching it — the “multitouch” function. That advance relied upon particular materials, as the screen is chemically strengthened, made scrape-resistant and embedded with sensitive sensors. Multitouch wasn’t new, but Apple understood how to build it into a highly useful product.

Imagine putting together a production system that could make 1.2 billion of these devices.
