AI Could Drain the Shared Expertise Pool Professions Need to Survive

The Tragedy of the Cognitive Commons

This conceptual paper introduces the Cognitive Commons framework, which combines commons theory, HRD scholarship, and distributed cognition to explain how rational AI adoption can deplete the shared expertise that professions rely on for renewal. It distinguishes Internalized Mastery from Distributed Mastery and introduces the Validation Tether, which shows that effective AI oversight depends on the very expertise AI may undermine. Early evidence from labor markets and clinical settings suggests disruption to expertise-regeneration pathways in AI-exposed sectors, and the paper identifies five factors that determine occupational vulnerability, proposing governance across organizational, professional, and policy levels.
