Columbia Business School’s Professor Rita McGrath spoke with The Wall Street Journal about how artificial intelligence is rapidly reducing the amount of work that can be billed by the hour—particularly in law, consulting, and other professional services. McGrath explained that as AI automates routine analysis, drafting, and research tasks, firms will need to rethink pricing models, client value propositions, and internal talent structures. She noted that the shift away from billable hours represents not just a technological disruption but a fundamental strategic transformation, requiring leaders to redesign how expertise is delivered and monetized.
