I suppose the thing is that a classically trained musician has their eyes on the sheet music, whilst also keeping an eye on the conductor, so they have to learn to play largely by feel with minimal glances at the instrument. Those of us without such training have the luxury of being able to either watch our fingers or look at the audience, ideally one should do more of the latter than the former, apart from when you might be racing up and down the fingerboard. Let’s face it, staring at your fingers whilst working entirely within frets 1-3 is novice territory.
