And likely most skilled labor as well: https://www.youtube.com/watch?v=7Pq-S557XQU (Humans Need Not Apply)
90+% of law involves things like contract law and analysis of legal documents. All of that can be replaced by natural language processing, machine learning, etc. I envision "contract compilers" that produce contracts based on compact specs and other things in the near term (5-10 years out) followed by total replacement of most lower-level legal work with AI/ML in the 15-30 year time frame.
In the end you will still have lawyers, but only to appear in courtrooms and do very high skill specialized legal analysis that involves a lot of conceptual thought. That will be a much smaller number of people than are employed in law today.
That's a lot of well-paying jobs that are going to vaporize.
