Why autosaged?
Give it 5 more years and a new generation will start being obsessed with the 2010s. And the older generation had vaporwave for instance. It goes much further than that too, this phenomenon of "faux nostalgia" isn't new.
It should be common knowledge that a "thing" becoming mainstream will most likely change, sooner or later, and its "fanbase?" can divide to those before and after the popularity wave. I wanted to write more but got stuck in a thought loop; it sucks that these "trend kids" don't care to educate themselves about what they like. They will move on and so will the trend, and on what website did you read this post? What was its original goal?
