finally, was this thing you beat the actual lawyer at in their specific specialty, since lawyers are often focused on particular aspects of the law?
IME, many lawyers who represent others also have fools for clients.
Additionally, you haven't given any of the details of your case, so I'm going to assume you were simply in a position where the facts of your case weighed heavily in your substantive favor, and no amount of legal maneuvers by the defendant would have made a difference.
There's nothing magical about lawyers. They are mostly just boring, studious people who excelled in non-STEM academics and were good at memorization and test taking. If you have a strong case, it won't matter very much who the lawyer is on the other side.
So? I beat actual lawyers in trials and hearings five times between 2008 and 2019. That last one was actually a team of attorney + advocate (senior bar member).
You could always "beat" them just by reading and preparing. Now, you+AI beat a lawyer. Tomorrow, do you really think that you+AI will beat lawyer+AI?
And once we stop getting well-trained lawyers (because everyone is just a meatbag accessory to an AI), whether you win or not is likely to be a coin toss.
