Different people are able to perceive to different degrees. Just as not all vision is equal for everyone, neither is perception. But diminishing returns seems obvious to me, and always did. The leap is great at the beginning, and while it's numerically even bigger at the end, we notice it less. You've got 3rd gen which you can practically draw in MS paint, 4th gen which looks orders of magnitude better, but can still be drawn in MS paint if you have talent, then 5th gen where the only reason it looks better is because it's in 3D, then 6th gen where it starts to actually resemble real life but blurry, then 7th gen is pretty much the same but not blurry, then 8th gen just looks a little crisper if you can make it out. 9th gen will be pretty much at the upper limit of the best of human perception to tell the difference, and from there, it'll just be improvements in physics processing and AI that'll be the difference from one gen to the next. Graphics never mattered that much, but soon they won't matter at all. This is the last gen that resolution will matter, next gen will probably be the last one that frame rate will matter, and we'll all look back at these graphics wars the way we look back now at the bit wars.
