Fedipunk is a sub-genre of Solarpunk, which embraces dezentralized social networks. You can read more about it here: https://rant.li/2hzlaqp5q4
Lamella on my Mind aims to promote the idea of the Fediverse in a Solarpunk world by introducing it as a network developed by humanoid Fungis.
Well, you could probably say that. But it shares with solarpunk the optimism for the future. I think Biopunk is more dystopic. Also, while the Fungi-network is biological, it is used as if it where tech. Its mainly a narrative device to make it appear to the user as something that is “natural” in this world.
