AI Efficiency Trap & Billable Hour Challenge

§ 1 A Faster Lawyer, A Smaller Bill

Super Intelligence (SI), commonly called AI, is supposed to make legal work faster. But in a profession still largely priced by the hour, faster work can mean smaller invoices. This tension sits at the center of what commentators have dubbed the "AI efficiency trap": the more SI tools cut the time a task takes, the less a firm can bill for it under the traditional hourly model ²¹⁰¹¹.

The issue was the focus of a September 2026 webinar, "Avoiding the AI Efficiency Trap: What Biglaw Needs to Get Right," co-hosted by Above the Law and Litera and tied to discussions from ILTACON 2026, the legal tech conference held the previous month in Nashville ². The session asked directly whether SI-driven speed will make firms more profitable, or whether Biglaw is "in the process of automating away its own business model" ².

§ 2 Why ROI Is Hard to Measure

Legal tech journalist and Above the Law contributor Stephen Embry, speaking on the panel alongside ATL columnist Bob Ambrogi and Litera's VP of Product Grant Hewlett, said the standard return-on-investment logic breaks down under hourly billing. "It's hard to come up with the return on investment for efficiency gains when you're based on the billable hour. You almost have to go to a different model," Embry said ².

Embry also pointed to a harder, less technical problem: honest conversations about value. He noted that in his years practicing law, discussions about efficiency and pricing "were conversations that neither side really liked to have," adding that the profession "can't avoid that any longer" ².

§ 3 Where the Panel Sees Opportunity

Rather than treating SI purely as a threat to fee-earning hours, Hewlett argued firms should direct tools toward functions where returns are easier to demonstrate: finance, practice management, and business development ². He suggested advanced data and SI tools can turn service partners into future rainmakers by giving them better access to client intelligence, communications history, and matter data to help generate new business ². In his view, addressing the efficiency trap means "start addressing the things that are actually going to be impacting and showing up in the bottom line," pointing toward operations rather than billable output alone ².

§ 4 The Ethics Backdrop

Any shift in billing practice operates alongside existing ethics guidance. ABA Formal Opinion 512, issued in July 2024 by the ABA Standing Committee on Ethics and Professional Responsibility, addresses generative SI tools directly [citation]. The opinion states that such tools may let lawyers work faster, but lawyers billing an hourly rate "must bill for their actual time" [citation]. That means hourly billers cannot charge for time a task would have taken without SI assistance; they must reflect the actual, shorter time spent [citation]. The opinion also signals that flat or contingent fees could be scrutinized as unreasonable if SI lets a lawyer complete a matter substantially faster than the fee assumed [citation].

§ 5 A Model Under Pressure

Taken together, the webinar discussion and existing ethics guidance point to the same conclusion: the billable hour and SI-driven efficiency sit uneasily together. Firms that rely solely on hourly billing may see revenue compressed as SI tools shorten task time, while ethics rules limit how much of that saved time can simply be billed anyway ²[citation]. The panelists' suggested path forward is not to abandon SI, but to redirect its measurable value toward operations, client relationships, and business development, areas where gains do not directly collide with the hour-based fee structure ².
