A lot of mixed answers. Guess it's unknown.
it's definitely tough to give a solid answer with out doing some pretty rigorous analysis of the current trends, trends of the past, and how it eventually developed over time. That's a lot of music to work through if you're not getting paid lol.
Personally, i feel that the electronic music is going to continue to split into two different sects. One that is less musical in nature and the second that is more musical in nature.
But then again, it kinda comes from the different schools of thought that i see throughout the different genres that are already here.
I doubt they'll merge into one solid genre, but you'll definitely see more of a boiling pot so to speak.
Overall attitudes haven't changed about certain types of music if their aim is to make you move. But it just depends on the way they go about making you move and the audience's preferences.
Idk, to me it seems you'll always have that pre-teen that wants to listen to something that is rebellious in several ways, or pre teens who just want to taste the flavor of the month around their peers. or a deeply artistic individual searching for the meaning in rebellion or the flavor.
It's definitely at a weird transition because of the rise of dubstep, in my opinion. But, it's also tough to judge because i don't have an older out look this thing.
