Messy Jobs: The Work That AI Cannot Reach

Messy Jobs, by economists Luis Garicano, Jin Li, and Yanhui Wu, argues that AI will not automate most white-collar work because many jobs are inherently 'messy' — involving coordination, negotiation, and human interactions. The authors use economic reasoning to show that as intelligence becomes cheap, judgment, coordination, trust, and responsibility become more valuable. The book features endorsements from notable economists and business leaders.
