As a former first responder, I'm interested in hearing more about how AI-powered ambulance services would work. (related question: will the 911 dispatchers be AI?)
Administrators, on the other hand, are a massive part of the costs in the health sector (IIRC the Obama administration chickened out on truly reforming healthcare exactly because the number of administrators that would be made redundant would tank the economy). A significant amount of administrative work can be automated.
