Dunno how accurate the info I had was but there was a figure in a doc I watched that about 80% of legal work was "discovery" which is not talking your ass off in court, winning over the jury but poring over documents, accounts, email and shit like that trying to build a case.
This process (80% of the stuff lawyers do) is about to get automated by deep learning systems which can do the job infinitely faster and an order of magnitude more accurately.
100% of lawyers with 20% stuff left to do should be interesting. I'm not thinking techno unemployment (That's call-center staff and burger chefs) more a case of less backlog. What's going to happen to the legal system once the backlog is reduced by 80%?
The lawyers will lobby for even more laws. Many of them will instead go into politics.

I'm thinking more along the lines of the School to Prison Pipeline you guys have going on over there. You could be approaching "peak-prison" where you can't build them fast enough. What happens then? Escape from New York?
