Postmodernism is seen as a theory for explaining 20th Century culture. With the 20th Century now behind us and a new century beginning, many have suggested that Postmodernism is outdated in our current world. Advances such as the internet have changed the way we live, making the world a smaller place but also making communication and interaction with things around us less intimate. Post-Postmodernism takes this as a key reason why a return to sincerity and authentic expression is the way forward for the 21st Century.
