You have absolutely no clue what is high profit legal work.
Partners at AM100 law firms doing Mergers and Acquisitions typically bill over $1,500 an hour and can bill as much as $3,000 an hour. They can have a dozen partners bill 100 hours a week for months at those rates. And you think divorce is high profit?
This is why nobody takes AI fan boys who think AI will take over the legal profession seriously.
You are talking about the low margin stuff that people wish they weren't doing, and calling it high margin. The margins aren't there. The typical cost of suing over a home loan is about $200k. Which is approaching the value of the loan in poor areas. The cost is in things like depositions, transcription services, document review, court appearances and a small amount of the cost is in the legal arguments after all the evidence has been collected and sifted through.
There is a case to be made that AI could be used for document review of finding documents and reviewing the latest case law, to find relevant cases, but you need to have something like a WestLaw database, that you double check each citation with. More or less having the AI point to the cases, and then have the cases pop in from Westlaw, so if it hallucinated, it is at least misreading an existing case instead of making up cases.
There is another problem with the current AI software in that they don't understand that lawyers work on different cases and have to not share information between the cases, but still share their general knowledge. That is a problem that is pretty easy to solve at a technical level, but less so at a cost level.
