I spent the better part of two decades coding on computers where light colours on a black background were the ONLY choice. Mix in the poorly formed characters, blurryness, and eye-strain INHERENT in the approach, I don't miss it.
I've come to really prefer dark text on a light background -- but then I still prefer monochromatic code since I find colour syntax highlighting to be UTTERLY USELESS since my eyes can't focus on / read the every changing rainbow-striping of the code. It's another of the things people constantly praise that I go "just how the devil do you even read that?!?"
Dark themes just make it worse, particularly with the "love" some people have for colour contrasts far, FAR, FAR below accessibility minimums. To the point I've sat there and watched people make mistakes they can't even see, and then rely on their "tools" to fix them or point them out. Mistakes they wouldn't even make in the first huffing place if they just used a colour scheme that was, I dunno.... LEGIBLE?!?
