Another successor to postmodernism?

Philip Galantar has suggested a successor to postmodernism called "complexism". Again, I haven't fully digested this yet, but it does seem stimulating. Here's a chapter on the subject he wrote:

Quote:
"As a central part of the art manifesto aspect of this chapter I’m asserting that it is time to go beyond postmodernism. Like all waves of philosophical skepticism, postmodernism taken to its ultimate conclusion leads to an intellectual and existential dead-end. And, indeed, even in the arts and humanities there is a vague sense that postmodernism has been “played out.”
