I plan to write a science-fiction novel with merfolk. Specifically, it will be solarpunk. The opposite of apocalyptic, it imagines radically hopeful futures. With people not being crushed by capitalism, they will have more time to pursue art and sport. Mermaiding is both.

Imagine a green and wholesome cyberpunk. What advancements would help you? The first one that I can think of is a version of a nictitating membrane, to protect your eyes from the water. Whether biological or cybernetic, would this mod be something you could get excited about? What else would help you be your truest self?
