Just because technology can do something, doent meant its always right

I think a desktop 8k, with that stupid cleartype disabled, is just perfect for reading .pdf documents with 2 facing pages.
At least I imagine so.as cleartype still has a minor enhancement on large 4k monitors and does improve 2k displays at the cost of that annoying color fringing around the fonts with fine vertical lines.

Honestly? No, at least not for 35mm and smaller.

Digital has surpassed film, especially in low light, where there’s no comparison. A modern DSLR or digital cinema camera can produce great images at ISO speeds film could only dream of.

Yes and no. First, just a quick reminder that the oft-cited figure of 21Mp for 35mm refers to 35mm photographic film, which is run horizontally through the camera, giving a 36x24mm frame, whereas 35mm movie film runs vertically, with a maximum frame size of around 22x16mm.

Either way, though, the maximum resolution and the typical resolution vary wildly. Only the sharpest, slowest of films (low ISO) get the maximum resolutions, but require tons of light. Fast (high ISO) films for low light had markedly lower resolution, and modern digital can easily exceed those.

Additionally, there’s a huge difference between the film negatives and a typical release print, which is many generations removed from the negatives: release prints suck. (I’ve gone to special movie screenings done with fewer-generations-removed prints, and the difference is striking.) If I had to guesstimate, I’d say a typical release print probably tops out at 4K, if that, and many aren’t any better than 2K.

Exactly
35mm capture can be around that 6-8Mp, it is also near the optics limit
But digital capture way outperforms it, and most movie grade 4-8k cameras will have bigger sensors giving way better quality than film
And when you project from prints, they degrade pretty fast. If you have just a few passes then you are surpassed by 4k, even if it was made to this high quality at start. And can end up worse than HD after a few weeks  :-//

Perhaps you can do a realistic 8K representation of the mushiness of a CRT picture :)
That yould really be pleasing to the eye, more than sharp pixels.

The difference is night and day between 720P and 1440p on a phone watching youtube.
You can tell between 1080p and 1440p however it's much less obvious and you kinda need high bitrate native content which you almost never have on a phone.
