You hit the nail on the head, there is an incentive to automate legal services ala legal zoom but for lawyers themselves the more tedious and paper based the process is the more they can make.
Hourly billing is (very slowly) going away. Fixed fee arrangements will be king (people want predictability). So then a lawyer will want to be as efficient as possible. The legal industry is admittedly behind the times, but they do continue to move forward.
