Saves your battery. Easy on eyes. Dark theme is just nicer, what am I missing?
1995/m here and I exclusively use dark mode. Preferably white text on a black background (sometimes called LED dark mode). I’m not sure if your generation + gender theory holds but I will say that the games and software I played growing up used a combination of dark and light for UI and menus.
Interesting point, maybe people with more gaming growing up prefer the dark mode. Much of the gaming era came around after my time!
