Postmodernism is a lot more relevant to the digital age than anything, imo. It emphasizes pointing out ways of thinking and doing, which I think is especially relevant when we are actually automating most of our ways of thinking and doing.
I know it gets a bad rap because of the ridiculous examples, but the real point of it engages the viewer into a serious kind of contemplation concerning the massive infrastructure that exists and how that shapes our culture, thoughts, understanding, action..
We have the expectation that the generations to come will accept this infrastructure and what it says about how the human mind functions. But much of it is founded on belief systems of how thought and action operate in the real world. Most of these systems are baseless, the idea of a base obfuscated only by the sheer complexity involved in understanding each layer.
