I think its because we have yet to really look back on the 2010s , im sure someone during the 90s felt the same way during the 90s as we do now.
To look back, what I think defines the 2010s is "wasted potential", I remember the vibe there was in 2009, 2010 and 2011, there was a genuine desire to make the world a better place, to dig ourselves out of the pit of terrorism, war and recession and get things back on track, it was honestly a pretty beautiful thing while it lasted, but then it got high jacked by evil militant leftists that just wanted revenge and here we are, worse off than we were in 2010, which is mind boggling.
Culturally when we entered the 2010s there was a strong desire to bring back some cool elements of older pop culture that had fallen by the wayside, a desire to "get the old band back together" among many creative types and franchises, fueled by things like Kickstarter, I still remember how fucking exciting it was when the news that Disney bought Star Wars dropped, there was literally a universe of possibility.
But then, instead of bringing old things back and doing them justice, things veered off into deconstructionist territory, aka "Woke", which in many instances has buried these beloved franchises for good, with Stars Wars being the biggest example.
Only Mad Max: Fury Road really gave us an idea what these retro revivals could have been like when done well, instead we mostly got garbage like Ghostbusters 2016 and The Last Jedi.
Somewhere out there is probably an alternate universe where the 2010s was an amazing decade we all dream about, but it wasn't this timeline.
Not really. Decades only get their stereotypes long after, like the years 1980-89 only slightly resemble "the 80s", and most of what we think of "the 60s" was 1967-69 and much of the culture was very different.
It's funny how that works, there's so many forgotten aspects of life in the 90s that I remember that aren't a part of the stereotype of "the 90s" today, the same will probably hold true for the 00s and 10s.
