Art after modernism

As I've noted in other threads, I'm reading Rushkoff's Team Human. Chapters 61 and 62 deal with art after modernism. As Abramson noted elsewhere, it shuns bi-valence, the traditional hero v. villain. It also shuns traditional plot structure which creates tension and release in a certain outcome. Rather it features ambiguity and paradox, replacing an omniscient narrator with points of view from multiple characters, no central one to subdue the others. Any contingent and temporary answers are arrived at via collaborative interpretation. There is no theory of everything, no assholon, no ultimate truth. Yes, that in itself is a metanarrative, but one more open and porous, more in-between, a cohesive, de/reconstructive hier(an)archical syntegrity.
