alt Hacker News> Too bad "tiny screens" pretty much do not exist anymore. Screens with hundreds of pixels on each side are very cheap already.
Find me a 0.66" OLED display for ~$1 that has hundreds of pixels on each side then.
> It reminds me people who research "colorizing grayscale photos", which do not exist anymore either (if you want a color photo of someone you met in your life, there probably exists a color photo of that person).
What train of thought led you to think people are primarily researching colorising new B&W photos? As opposed to historical ones, or those of relatives taken when they were young? You can take a colour photo of granddad today but most likely the photos of him in his 20s are all in black and white.
If you know a person who is 70 years old, they were 20 in 1975 - color photos existed back then.
Every grayscale photo of someone famous has already been colorized during the past 50 years. If there are only grayscale photos of you, you were probably born before 1900, and all your friends or your children (who might want to colorize your photo) are probably dead, too.
