I suppose one way is that the Lawyers and Legal Assistants use Legal AI as a replacement for standard search. Instead of parsing content and creating new notes, let AI search and create but humans spend the same amount time instead for verifying what was created.
That way the billable hours can match, but like the article says, who does this benefit? Ultimately the transfer of time to another task will keep law just as expensive. Perhaps there is room to save time on verification vs creation. Is it worth all the investment though?
