"Large increases in software productivity since the 1990s were accompanied by rising, not falling, employment in web development" [1990s]
The article uses multiple historical cases (software, accounting, manufacturing, retail, logistics, spreadsheets, ATMs, newspapers) to establish a general principle: task capability is decoupled from employment outcomes. The mechanism is demand elasticity—sectors with unsatiated demand (healthcare, professional services, tech) see employment rise despite productivity gains, while saturated sectors (manufacturing, retail) see employment fall. This pattern is presented as predictive for AI's labor impact across different occupations.
