I probably can't see even 320x240, but that doesn't mean I don't like having the extra pixels since I don't stare at one spot the whole time. Upgrading to 4k felt extremely liberating compared with 1080, IMO - productivity is so subjective I'm not sure it can be said scientifically that more screen real estate is necessarily pointless. Plus, imagine a screen the size of a whole wall - if you want to project a life size image of a desktop computer onto it, you can only ever render some small subset of your pixels as its screen, so if you want to render it with a 1080 display you'll need a lot more than 4k. The number of pixels one needs is highly dependent on what one is doing with those pixels.
