Regardless, the stethoscope has (for better or worse) already been replaced for a while, at least for in-hospital care at larger US/Canadian community/academic settings, by chest x-ray and/or the increasing straight jump to CT pulmonary angiography. In hospitals, sure, but GPs don't have access to those. At least in my experience "is this a bad cold or is it bronchitis" gets answered with a stethoscope.
