Pharma ads as AI health advice will be super profitable. AIs are very engaging and able convince people they have a disease, inadvertently coach them on how to mislead their doctor, and how to fast track diagnosis supporting their specific meds. The only guard is to have detailed manifest of exactly what was used in training. Even that may prove insufficient as "final assembly" has emergent properties. For example, omitting case reports of severe outcomes for a given formulation. Bias can be constructed.
