These resolutions have got to come to an end.
1080p was awesome, I have to be at about 2.5 meters of my 50" TV to distinguish the pixels. With 4K, I have to be at much less than a meter with the same size, which will never happen because I care for my eyes. All that amounts to saturated networks and more time to export and etc. It's NOT necessary.
HOWEVER, an 8K computer could be used to generate a 4K video, and have the preview of your video take the quarter of your screen. If it's about something else, I'm not jumping in this train.
