I haven't criticised anyone merely stated my opinion that it's crazy to shoot video or still photos at less than the full quality that your camera is capable of.Maybe you are watching too close! The fact is for most people HD is good enough for video and 8mp for stills. That doesn't mean there's something wrong with them.What consensus? If you can't see the difference between 4K & 1080p either you need glasses or your screen is too small or you are watching from too far away.4k is old hat already, we will soon be expect this to be 6k plus and calling 4k an inferior format. Plans to have a format that will have long term immunity against being comparatively poor are unrealistic.
that said there is a growing consensus that most folk are not able to discriminate between 4k and HD content, and for many HD is equal to the task and it is a thinking error to driven by marketing propaganda to think otherwise.
One of my cameras is 42mp. Do you have a camera with that much resolution? If you don't and can't see or don't care about the difference between 42mp and 20mp for example you must need glasses or are looking at too small a size.The commonest size for HD TVs was 46". Today the commonest size for a 4K TV is 60". The difference is chalk & cheese. 4K is like looking through a window.
My point is stop criticizing someone else who disagrees with you on the need for 4K. It's none of your business what they like. Instead you shoot 4K and let them be happy with HD.
I used to shoot stills & video professionally with FF cameras including 36mp Nikon D810 & loved the resolution & dynamic range but nowadays I prefer to compromise on size & weight & convenience with 20mp Sony RX10 & RX100 cameras. However just as I never used the Nikon with anything other than FX full frame lenses I don't use the 1" sensor cameras at anything less than their full capability. You can never add back detail that you didn't record in the first place.
