I feel like finding and citing appropriate law cases would be a great way for AI to be used, especially because the bullshit legal-ese that surrounds everything in court cases is so spectacularly opaque and trivial that you have to pay out the nose just for someone to parse through all the bullshit... Like, lawyers shouldn't even be a thing you need unless it's for some really complicated case. The courtroom should be a place where an average citizen could speak for themselves.
Also, as someone who studied medicine... Do you know how often doctors will take a patients history, step outside the exam room, and then google shit? I don't want to imply that they don't know what they're doing, like, you need to study medicine to know what to google, BUT... they still be googling shit. I think AI could be trained to ask the same patient history questions that a nurse asks. Then using the answers to those questions, then they can provide some feedback, with a big ol disclaimer that it's NOT to be taken seriously, and you should consult with a physician.
