Enough with the trope of jazz being a sick patient, or the other one of jazz being an inviolable, sacred art form. Both are, essentially, irrelevant to most musicians and listeners. If somebody wants to mix jazz & hip hop it's neither the salvation of jazz nor its death knell, it's just another episode in a long and multifaceted history of the music in relationship to other genres.
This kind of stuff seems "important" to those of us who follow the scene, but I think it's meaningless to most listeners, as well as artists who will, for the most part, choose to follow what they think is right for their own careers, be it with a focus on artistic integrity, or commercial success, or both. I think it's like all those petty battles in academia that seemed important when I was in academia, and are essentially off my radar now.
