Well, we knew since the "Roko's Basilisk" debacle that they're prone to magical thinking.

"This is also how I learned one way that Photoshop was for professionals and GIMP & ImageMagick weren’t; At the time (and this was years ago, to be fair), Photoshop dithered by default when going from 16 to 8 bits, while those popular open source tools did not and also did not even have good ways to do it manually by adding the right amount of noise before changing the bit depth."

Yes. Photoshop does the correct thing when going 8bit via the "Mode" menu. On the other hand, if you do "Export As → PNG" and check the "Smaller file (8-bit)" checkbox, it does NOT dither, and it produces banding artifacts.

Absolutely! Higher precision is always better. But if you must go as low as 8bits, you should dither.

8 bit per component = 0-255 red, 0-255 green, 0-255 blue

Like ~99% of images you encounter on the Web.

Yeah. But even if you stay in the digital realm, dithering is necessary at 8bits per component. Consider that a grayscale gradient can only have 256 distinct levels.

Every image should be dithered below 10 bits/component to prevent banding artifacts.

Does this look like a bad place to live? https://en.wikipedia.org/wiki/The_Round_Houses_in_Moscow

Easter European commie blocks usually have strategically placed parks, shopping, kindergartens, schools, medical facilities within walking distance. For this reason, apartments in these areas are actually appreciating at a faster rate than housing built from the 90s onwards. It's hardly a Pruitt-Igoe.

That's patently untrue. Otherwise we wouldn't need concrete sealants.
