AI health coaches aren’t just for athletes anymore. They’re starting to handle the day-to-day interpretation, advice, and treatment adjustments that once required doctors.

Lawmakers are moving to ban AI-only insurance denials, requiring human sign-off for every case. It sounds compassionate, but it locks us into the same slow, opaque, costly system.
