Why Chatbots Remain Dangerously Unreliable for Medical Diagnosis

LLMs generate confident-sounding but medically incorrect information, creating real liability risks as patients increasingly turn to AI for preliminary health guidance.

Systems adopting chatbot triage without human verification checkpoints are outsourcing diagnostic gatekeeping to technology that cannot distinguish between plausible-sounding fabrication and fact.
