Machine learning has entered the world of the professions with differential impacts. Automation will have huge impacts on the nature of work and society. Engineering, architecture, and medicine are early and enthusiastic adopters of automation.

We argue that in the law and the legal profession, the role of lawyer as trusted advisor will again emerge as the central point of value.
