I argued with someone (online) about a ChatGPT diagnosis recently. They have back pain and they've had an MRI but the scans (shared online) don't show any significate disk bulging and no herniations. They put their symptoms into ChatGPT and got a possible diagnosis of a disk herniation along with a treatment of a microdiscectomy.
Despite the fact that a couple doctors have told them they don't need surgery they are convinced that they do. I understand that they are desperate for a solution to their pain but they are now doctor shopping until they can find someone willing to perform a procedure that ChatGPT suggested.
People are already being misled by these systems.
