The amount a doctor can learn about the functioning of one's heart and lungs via a cheap and simple tool like a stethoscope is amazing, and certainly nothing to look down on. Ultrasound tools may well one day be as commonly used but while ultrasound and other imaging tech can provide images and details stethoscopes cannot, they in turn cannot give the doctor any information about how ones breathing sounds, and cannot provide the instant and visceral connection of hearing your heartbeat directly.
Simple tools like stethoscopes are critical to medical care precisely because they are so cheap, easy to use, flexible, reliable, portable, quick to deploy, and give a direct human connection between doctor and patient. Why would you ever want to replace it? Supplement, sure. Improve, absolutely.
