Two arguments about the same future.

Oxford University Press July 2026

Superjustice

with Samuel Becher

Today's legal systems were not built for the AI age. Superjustice reimagines them. A book about what justice can become when the constraints of scarcity, delay, and inconsistency are relaxed by computation.

The Legal Singularity: How Artificial Intelligence Can Make Law Radically Better
University of Toronto Press 2023

The Legal Singularity

with Abdi Aidid

How AI can make law more predictable, coherent, and fair. An argument for a future state in which law becomes functionally complete, and for what a profession built around that transformation will look like.

Winner, 2024 AAP PROSE Award. Shortlisted, Donner Prize.
