Dark mode is for people who have their monitor brightness set way too high. I'm serious - try it. Only issue is that some monitors' dimmest setting is still too bright. You could also get a user-styles extension.
I know that there are probably extensions etc but I'm in my bedroom now and the room is not lit like an office and the site is really bright :) For us "geeks", although I appreciate the minimalism, I'm sure that we enjoy dark theme everywhere.
so turn the brightness down
