Solarpunk is probably the most genuinely punk of the punkpunks since cyberpunk. Punk doesn’t mean pessimistic, it means anti-authoritarian and critical of mainstream society. Solarpunk is absolutely that, and its optimism is a part of what makes it punk, because mainstream society is giving into authoritarianism out of an overwhelming sense of pessimism. It is, however, a new wave of punk, critiquing postmodern sentiment in the same way the previous wave critiqued the then-dominant modernist sentiment. We are post-postmodern now.
