The AI boom is creating a generational divide in software jobs: US software developer employment for those aged 22-25 has declined -23% since November 2022, when ChatGPT was launched. At the same time, the 26-30 age group has seen a decrease of -5%. By comparison, employment among software developers aged 41-49 has risen +18% over the same period. This creates a 41 percentage point gap between the youngest and one of the most experienced groups within the same profession. Meanwhile, early-career workers in the most AI-exposed jobs have experienced a -16% decline in employment relative to less-exposed occupations and more experienced peers since November 2022, even after adjusting for firm-specific shocks. By contrast, employment among workers in less AI-exposed fields, as well as more experienced workers within the same occupations, has remained steady or continued to grow. The AI revolution is wiping out entry-level tech jobs.
