AGH Notation and playing by ear

How the hell have we gotten to a point in musical instruction where people can’t even fathom how one learns to read music AND play by ear? Holy crap. Are we really that bad off where these things seem so polarized that we can’t even conceive of them coexisting in the same brain without violating some physical law? This is ridiculous. This is beyond ridiculous! Do we really think that musicians are automatically in a situation where we have to choose between being mute or illiterate?!

Anyone who actually asks this question should … well, okay I can’t think of anything that matches the crime in this case. Holy mother of god, people. I can understand how someone would naturally lean in one direction or the other, but to introduce the word “only” or to imagine that it is impossible to do one if one learns to do the other is just … agh.
