I used to be quite fond of the amber CRTs, and still am from an aesthetic point of view. Also, for roughly my first decade of programming I used white text on blue background almost exclusively. So I get those who like dark mode. But eventually me and my eyes got older.
yeah - I find as I get older, I prefer a darker environment for working on the computer (turn of the room lights, etc) and a bright(blinding!) environment for working with my hands ;-) (Where did that #%$#% screw go!)
I also find, I'm _waaayy_ more annoyed by smudges on my glasses then when I was younger.
