Healthcare has always run on two currencies: information and trust. Patients hand over their most sensitive data, diagnoses, genetic profiles, mental health histories, on the assumption that it will be protected and that the people (or systems) handling it will treat them with care. Artificial intelligence is now reshaping both sides of that bargain at once. It’s becoming healthcare’s biggest new attack surface, and simultaneously one of its most promising tools for restoring the human touch in clinical care.
