I think the reason that I like dark mode is that I have had floaters in my eyes since at least age 14. They stand out against a bright white window background, but I don't notice them at all on a dark window with light text.

Or maybe it's just because that's how IBM PC DOS, BASICA, etc., as well as the VT100, VT220, VT300s that I used did it.

(Also, I think displays should paint with light, and having a white background is painting darkness on a computer screen. It's particularly bad for presentation slides. A light background just screams "PowerPoint presentation".)
