Reading the posts quickly, I found myself in agreement with what Oracolo said, but the problem, besides being one of convenience—having things at your fingertips without lifting a finger—is also strictly linked to school, culture, and social image.
Personally, having gone to listen to the orchestra several times, I can tell you that if I were to rely solely on listening, it is better heard in a recording than live. In a recording, one can catch nuances that are not easy to hear live. An orchestra's recording is, in my opinion, many times more "detailed" compared to listening to it live. We don't struggle to say the same for other genres, whether it be pop, rock, jazz, or whatever you like: it is a fact that a CD sounds much better than a live concert where there are acoustic issues, where singers are not perfectly in tune, where the sound production itself uses inferior technologies compared to those used within recording studios, etc. etc. In addition to all this, speaking always of classical music, we must also remember that on the tube [YouTube] you can find the same concerts played by different orchestras, conducted by different conductors, some historical...
Regarding scores, the same argument Oracolo made applies. Why go and buy the sheet music if for the same composition I find at least 5 different editions on IMSLP? (I will tell you that, barring rare exceptions, I am still fond of the bound book rather than loose sheets that will inevitably get mixed up around the house).
The problem, therefore, in my opinion, lies in the models that this society provides, and there are several, especially during adolescence where the foundations of future character are laid. The "Cool" model (recognized by a fairly large statistic) is the handsome kid who wears designer clothes, smokes cigarettes, stays out late at night (not to study but to hang out), is good at playing soccer, has a modified scooter, goes to the disco every Saturday to blast his ears with 135 dB, etc. etc.
The "good boy" model, on the other hand, is the one who studies, who at most when going out goes to eat pizza with friends and then a quiet pub, returns home at 1:30 AM at the latest (at 14 years old, what do you expect??), has passions and cultivates them with dedication, etc. etc.
The problem is that kids follow the first model much more than the second; therefore, we should now move to considering how the elements belonging to the first model look at those of the second...
Studies classical music? He's an idiot!
Good at school? Good for him, in the end he'll have more pieces of paper to wipe himself with. I'll be a bricklayer but I'll earn more than him (given the current state of things, this might even be true).
Returns home at 1:00? Think what an imbecile, he's missing the best part: women, alcohol, and the disco.
With this kind of mentality, it is normal that contexts unsuitable for these people, such as the theater, are destined to draw their last breath. Today's youth only think about going dancing or playing soccer, and women about being TV models; these are the highest aspirations in life... easy money. The theater of yesteryear has become the disco of today. The influx of people has all shifted there. The healthy entertainment of the theater is today replaced by these environments that teem with prostitution, drugs, and alcohol.
Pertanto I believe that the problem, the real one at the root of everything, is due to a socio-cultural factor.
With minds like these, it all ends. The world stops and begins to regress.
