I realize its not a technical publication, but this piece is real hand wavy.<p>Yes, a modern economy consumes energy reduces local entropy of atoms though agriculture, transportation and manufacture. This can be considered computation.<p>But then: "Late in the last decade, I developed a mathematical technique that can be used to characterize an economy’s ability to produce products. This measure of economic complexity, which makes use of information about the diversity of countries and the ubiquity of products, explains a substantial fraction of a country’s level of income, but it also explains future economic growth."<p>There is no substantial explanation of this measure and how it is constructed. If it can't be stated simply one suspects it is subject to manipulation and its predictive power might just be an artifact of its construction.
