^^^^Honestly, I think the producers and the listeners ARE the theorists of contemporary "noise" music. The canon of harmony isn't just defined by what old dudes say in classrooms; I read about the ten million steps it takes to get a kick sound or a weird robot noise and just go "damn".
The bounds will continue to be stretched in the underground, and popular culture will catch up eventually. However, with such easy access to a wealth of information due to the internet and mass media (I'm including sounds, sights, etc.) people will find it much easier to plant their feet in whatever niche they desire, at the same time others will find it easier to discover newer, stranger things.

I think you might be over-Romanticising a bit. I'm reminded of the complaint/argument I hear about ART/MUSIC BEING DEAD, WHY COULDN'T I HAVE BEEN BORN 2000 YEARS AGO WHEN PEOPLE WERE MAKING REAL ART and usually they cite some popular thing as an example of our undeniable decline. So, the face of Pop Culture is shallow and void of merit? Uhh, duh, that's almost the definition. I don't mean to skew your argument or put words in your mouth, I'm just making a comparison here.
I really don't see what's declined about music. It's more accessible from both an input and an output standpoint. It seems like anyone with the attitude could put things out there, and music of all kinds is made more and more public for listeners. If anything it's gotten MUCH better. Improvements and innovations can be made on a vast scale, and much faster due to instantaneous communication. Joe Schmo can play his 4 chords for youtube, and little Einstein can build a bomb in his DAW because society pretty much lets people do these things. So what if most people wanna hear robot-lovin' or empty club songs? It was pretty much the same 200 years ago, you really only hear about the stuff that was good because...it was good. Just like throughout history, what is deemed important in the progression of things will survive, everything else will likely be lost only to people who really care, but with wikipedia anyone can become an armchair scholar so 200 years from now there will probably be some neckbeards debating the merits of Skrillex and his impact on western culture.
