There is a big danger in this line of thinking. Pretending like we don't need to inherit a lot from the previous generations, or from people who think different from us in our current time, is willful ignorance. Every wild-eyed utopian who has striven to rewrite all of the rules has tended to fail pretty badly and has also tended to bring a lot of other people down with'm as well.
We do not need ideologies that call for full breaks from the past any more than we need ideologies that offer no improvements.
Taking over from the previous generation and moving things in a new direction is something that should be carefully considered and by getting as much feedback as possible. If revolutionaries actually listened to the people around them, we'd have a much better world out there...
I'm afraid that current trends have done a lot of damage to a bunch of existing cultural institutions. An easy example of this for readers of this forum would be the music industry. It has been a full-on technological assault which fragmented everything. The sales, the business and the artists themselves were absorbed by Apple, Facebook, and Google and a select few other social networks.
Art needs to be on the outside looking in, so it can properly reflect on society. And art should find it's way in to everyone's hearts, no matter their profession or specialties, so don't think I'm just talking about musicians here. And even within the scope of the music industry the "slacker middle class musician who should just get a programming job" is a really easy target and a huge straw-man.
You're gonna have to go out and define the word "art" on your own terms. Funny enough, you actually have to go out looking for it, it's not just gonna be whatever you read on Wiktionary.
I'll give you a little hint though. Wanton destruction of our cultural heritage is pretty much going in the exact opposite direction.
