Only in retrospect, a lot of the differences are exaggerated the further from them you get. Late 80's to early 90's really blur together, and until 9/11 happened 2001 didn't feel that different from 1998 (people where stilling using pagers and listening to the spice girls). In a couple years teens will be opining about how great the 2010's were with Adventure Time, the ps4 vs xbone console wars, the weird Brony phenomenon, and back when facebook was "good". By the time we're all old the 10's, 20's, 30's, etc. will have have distinct feels and nostalgia.
I think most of it is that history always feels in the past no matter how recent it objectively is. The 70's might as well have been when the pyramids where built as far as I'm concerned, and yet kids graduating highschool look at me like I'm Methuselah if I mentioned remembering 9/11 or owning a gameboy. The human mind just can't quite grasp the passage of time before it existed to experience it.
