This pattern is consistent with GenAI acting as seniority‑biased technological change: it substitutes for junior labor (or reduces the need for it) while leaving senior roles relatively intact.
Outlook
PessimisticSeniority-biased displacement harms young workers' career entry and development opportunities, with potential long-term effects on earnings trajectories and career ladder accessibility.
Potential Data Sources for Validation
Firm-level hiring data (job postings, resume data) should show sustained relative decline in junior/entry-level job postings and hires in GenAI-adopting firms versus non-adopters, while senior postings remain stable.
