Dark mode was a mistake. Early LCDs were dim so everyone cranked up the whites to make up for it. Now LCDs have caught up and it burns a significant number of peoples eyes, so we increasingly have to support two modes. Apples comically ugly dark mode icons shows how hard this is to do well.
I think the ideal thing to do would be to move back to greys as the base color for computer interfaces, like we had when bright CRTs were the norm. This has the added advantage of allowing depth affordances in UI elements, which we should also bring back.

Yeah, but it uses too many resources on my 4.4GHz Ryzen with 32GB of RAM. I wonder how Apollo was able to do this on a 20 MHz 68020 with 4MB of RAM while running a network distributed multiuser, multitasking OS. /s
CRTs also had easily adjustable brightness and contrast dials, so everyone could always quickly adjust to their preferred setting for black on white or vice versa.
Regarding the BeOS screenshot: mind that this is not regular BeOS, but the OS X-like "Baqua" appearance of the eOS 5.1d0 developer release, which never saw a regular release.
(I'm taking no offence, but it may be important to point out what's what, now that image references are becoming as inevitably as increasingly unreliable, as for "AI".)
