BigLaw as bottleneck for complex legal work
Current factComplex legal work historically required the leverage of a large firm because only BigLaw had the associate infrastructure to do due diligence, document review, and analytical workload at scale.
AI tools (Harvey, Lexis+ AI, Westlaw Edge AI, general-purpose LLMs) allow smaller firms and in-house teams to do work that previously required BigLaw infrastructure. Work redistributes from BigLaw to in-house counsel and to solo/small-firm lawyers.

Low risk on direction; moderate risk on magnitude
Aggregate U.S. law-grad employment at record high (NALP 93.4% Class of 2024) — narrative is redistribution, not contraction. Solo practice with general-purpose AI carries elevated quality risk.
