This article misses some huge innovations that have taken place in manufacturing and other heavy industrial areas. Take just one example in 3D printing. When this technology matures, the result will be no less profound than the invention of spare parts (hard to believe, but the idea of standardized parts that could be replaced when worn out is relatively new - few hundred years). Imagine a house that builds (or prints) itself? Today that technology is already getting a lot of adoption in aerospace, where the waste produced by machining is so expensive, it makes the costs of new technologies look like a bargain. Another good example is our ability to process data. The old saying goes: "Knowledge is power". Well, today we can process petabytes of data and extract knowledge out of it as routinely as flying from SF to NY...
