Artificial intelligence is automating routine legal tasks traditionally performed by junior and summer associates at major US law firms, disrupting the established training model for future partners [1]. Firms rely on junior associates to handle routine legal work not only to bill clients but also to gain the skills necessary for advancement to partnership [1]. Experts warn that automation threatens this training pipeline. "If more and more of that work that trains junior associates is being automated, then there's no real material anymore for them to train on," said Nik Guggenberger, professor at the University of Houston Law Center [1].
Leading firms have embedded AI into workflows and client portals to capture and automate lawyer expertise across research, document review, case law analysis, and litigation preparation [1]. Judges have begun using AI to draft and summarize legal opinions, though this is at an earlier stage [1]. Research by Stanford Law professor David Freeman Engstrom indicated firms are "getting ready for a world in which you need fewer human lawyers," highlighting the shift toward AI efficiency [1].
Some firms have already cut jobs due to increased AI adoption. Clifford Chance announced job reductions in 2025 citing AI-driven efficiencies [1]. Major firms have also slowed hiring of associates and reduced summer associate programs as automation reduces the demand for entry-level work [1]. Despite concerns about declines in traditional jobs, others see a different angle. Tiffany J. Tucker, assistant dean for career development at the University of Houston Law Center, said, "If you don't have prowess using AI, you're going to be left behind," pointing to new job opportunities for AI-literate law graduates [1].
In line with this, A&O Shearman and Harvey announced AI agents designed to handle complex legal workflows both internally and as products offered to clients and firms [1]. This signals a shift toward integrating AI as a core legal tool beyond just routine tasks.
The automation of junior lawyer tasks challenges the long-standing practice of using entry-level assignments as both billable work and training ground. Firms face the task of balancing efficiency gains with maintaining a viable training pipeline for the profession's future leaders [1].
