I think I'd like to see what people would do in their leisure time or domestic work . You see so many stories about travel and war, but you rarely see people interact outside of that. And if you do, it's usually not made unique for a setting that isn't Earth.
What cutlery do they use? What does a morning routine look like? In a world where fire magic is commonplace, how do they cook? How would those things evolve over centuries?
Fantasy especially feels stagnant for this, but I think sci-fi is guilty of this too. Are there things in specific works where an innocuous detail made you wonder more about how a setting worked?
More capitalism and more jank. I want car crashes because the bus driver had an OTA firmware update fail and his legs get bricked. I want cybernetic eyes that keep getting cool new features but your vision keeps getting shittier after every update because their memory is too low to force you to upgrade to a newer model. I want cheap prostethic lungs that run on disposable batteries and only let you sorta breathe, because the good ones are artificially expensive because of a big stock buyback. And I want brain implants that replace your dreams with ads.
