How powerful are today's AI tycoons compared with past industrial titans?
Core argument: John D. Rockefeller's peak wealth equalled roughly 1.5% of American GDP, and Elon Musk may be richer still depending on how his wealth is calculated, though The Economist's ranking places Henry Ford as the most powerful mogul America has seen.
A paper by Ufuk Akcigit points to the crucial role of so-called “transformative entrepreneurs” in turning inventions into long-run economic growth. In short, prosperity requires tycoons. To understand how the AI magnates compare with business titans through history, The Economist examined 11 technological waves in America over the past 150 years, from railways to the internet. For each, we picked the top five people responsible for the control, distribution and popularisation of that technology. We quantified the power of each by looking at the revenue, employment and market value of their companies at their peak, as well as a subjective assessment of the degree of corporate control held by the tycoon, along with their personal wealth. Riches alone would not capture the full extent of a tycoon’s power. At his peak the wealth of John D. Rockefeller, founder of Standard Oil, was equivalent to around 1.5% of American GDP. Mr. Musk may be richer still, depending on how his wealth is calculated. By our ranking, however, Henry Ford is the most powerful mogul America has seen so far.
