Not sure if the 'Metamodernism' moniker is going to stick. I am reminded that 'Poststructuralism' was once called 'Neostructuralism'.

I've written a recent Medium article about what happens after Postmodernism. It draws from Ken Wilber's Integral theory, but makes a new assertion of where we are going as a society.
