As a CTO of an Ai first law firm I would like to add that most human lawyers are absolutely terrible. We review 100s of old contracts every week and most of them have 10-20 serious drafting errors on them. The most common ones are of the order of defining the same concept like 'a working day' in various conflicting ways without every specifying when which of the conflicting definitions should be used. Lawyers still have something to add to process but for every time they catch AI out on them, the machine is usually already 10-1 ahead.
