This could potentially increase the number of useful questions being asked. My spouse is a physician. Recently she had to answer a phone call from a patient in the middle of the night where they were asking a question from a party about something non-urgent for their child. In another case, she got called by a parent at 2am because their kid was having trouble sleeping but nothing else was wrong with them (welcome to parenthood). If people had to pay, maybe they would _think_ before asking questions.
I've been in meetings with healthcare providers about incorporating LLMs into text-based patient-physician messaging to improve triage and routing. It is just overwhelming for many providers. A large percentage are getting burnt out, and much of their time is uncompensated.
