Not the worst? 48th percentile is basically "average lawyer". I don't need a Supreme Court lawyer to argue my parking ticket. And if you train the LLM with specific case law and use RAG can get much better.
In a worst case scenario if my local lawyer can use AI to generate a letter and just quickly go through it to make sure it didn't hallucinate, they can process more clients, offer faster service and cheaper prices. Maybe not a revolution but still a win.
