Expert system could be a great help for lawyers. Not in this implementation or role, but like an intelligent search engine for laws and cases. Systems like IBM Watson which would go to lawyer school and sip through years of cases. Not saying it would be fantastic, but at least it's a knowledge based system. ChatGPT... well, it's known to make stuff up, like citing fake sources in generated research paper. Would be fun for a lawyer if it cited a fake court case.
