Now they're a dime a dozen. Even 4k is beginning to settle down, and 8k is starting to be pushed. That will be good for when your nose touches the TV screen while sitting on your couch. Hello 16k! For when the human nose has flattened itself to an even smaller dimension due to being pressed against the TV screen. Human eyes are only SO good. Increasing screen resolution to ridiculous amounts does not make your eyes any better.

Quick check using the numbers tossed around a few years back when arguing about Apple's Retina displays was popular says a 70" 4K screen is "retina" at a distance of 55.32 inches (140.5cm). I don't know about you but the chances of my nose touching the screen at that distance is pretty low. No puppets in my ancestry.
A quick measurement says the distance from my favourite love seat to the TV screen is ~210cm so a 1920 x 1080 70" screen is not "retina" at that distance -- I'd need to move back another ~70cm. Now an 88" 8K OLED display... 33 megapixels just about matching high end DSLR sensors.
