Modern medicine has some aspects that are miraculously good and it is easy to fall into the trap of thinking that those are representative for all of medicine. It's a kind of halo effect bias.

In my opinion the most amazing thing still is antibiotics (and vaccination). Treatmeant of war/vehicle/sports injuries taking the second place (including anesthetics). Both can take people from a path of sure death within hours or days to often complete recovery within weeks or months.

If that is the performance expectation of the general public for all of medicine, then it certainly is overrated.
