Last time things kinda looked up was in 2016 for me, but Donny quickly showed that he was just another useless swamp monster. I'd go so far as to say that the release of the PS3 was when the spiral started to become apparent. That was 2006. It was incredibly slow, though.
I don't remember much of the early 2010s (mostly because I was an underage retard trying to get a girlfriend), but after leaving highschool in 2014 and becoming lucid, slowly starting to understand things, that's when I started to become aware of the fact that something was changing. 2015 I remember well, because the beginning of that year was the first time I noticed that with every new year, people appear to collectively lose their minds one step further than last year, never fully recovering from their slip into madness.
The drop from 2015 to 2016 was crazy, then it got somewhat quiet, perhaps because people had Donald Trump to hate. 2018 to 2019 was bad, 2019 to 2020 was worse, 2020 to 2021 may as well have been the end times. People have turned into total cattle.
