Totally disagree. Solarpunk is providing an out for the future that cyberpunk warns us about. Hoplessness is endemic amongst the young people in Western socities at the moment. A hopeful vision for the future is something necessary to pervade the public consciousness and create a better future in reality. It honestly happened with cyberpunk already. The aesthetic was taken up subconsciously by designers and engineers and actualised into reality. The same could happen for solarpunk.
