Because much of the younger generation has never heard true high fidelity and most don't have the patience to sit and really listen? Further, most are wanting (and more familiar with) making a wi-fi or Bluetooth connection to EVERYTHING rather than reliable, quality wired connections and demand everything they do be connected with their brain...which is located in that flat, rectangular device in their hand.
OK, that was a bit harsh. Just having an senior observational moment.
