AI Exposure Moves Inside the Job Description
Across 50,000 postings, exposed activities decline only mildly while employers increasingly ask workers to perform them with AI.
Summary
Across 50,000 postings, exposed activities decline only mildly while employers increasingly ask workers to perform them with AI.
Researchers extracted responsibilities from 50,000 job advertisements at 33 firms from 2023 through 2025 and mapped them to the O*NET Intermediate Work Activities taxonomy. Explicit mentions of AI rose 66 percent, although much of that increase sat outside the responsibility descriptions themselves. Within advertised duties, activities measured as more exposed to Copilot and Claude usage declined mildly as a share of responsibilities but increasingly appeared alongside explicit AI-related work. The observational design does not establish that AI caused the changes, and the firm sample is bounded, but it suggests adaptation inside roles rather than a simple disappearance of exposed work.
