The Secret History of Computing
How unemployed hairdressers, ancient grammarians, and Victorian visionaries built the logic of modern AI In the turbulent aftermath of the French Revolution, a forgotten project birthed a revolution in thought: Gaspard de Prony's Cadastre (1791–1801) transformed unemployed hairdressers into "human computers," applying Adam Smith's division of labor to mathematics. This "calculation factory" inspired Charles Babbage's Difference Engine, while ancient India's Pāṇini had already encoded language into algorithmic rules two millennia prior. Ada Lovelace then envisioned machines manipulating symbols beyond numbers, anticipating artificial intelligence. This article traces the recursive thread connecting Pāṇini's grammatical sūtras, de Prony's industrialized arithmetic, Babbage's mechanical gears, and Lovelace's symbolic abstraction to modern AI's tokenization, parallel processing, and attention mechanisms. By retaining historical cont...
