ELI5: Why do most laptops still have a 1366x768 screen resolution while most smartphones are already at 1920x1080 and up?

Resolution is also about viewing distance.  You can get away with a lower resolution display if you are sitting further away.  However, when trying to make out text on a small 5" screen 1 foot from your face it helps to have a higher res screen.  A lower resolution on a larger display that you sit 2 feet from is more acceptable than a low resolution on a smaller display you hold closer to your eyes.

A lot of it now is also marketing and becoming overkill, but it is more helpful to have a higher resolution display on a cell phone than on a laptop.  You don't really need to not see a pixel on your phone, but that was the reasoning between the resolution wars on smartphones.  There never was a resolution war on laptops.
