Does it seem like nostalgia for the 2010s is emerging faster than expected?

I'm sure most people here would be familiar with the "Y2K" movement, which I understand as the general popularization of nostalgia for 2000s internet culture and related aesthetics. Some musical artists have even capitalized on this and have made Y2K a part of their brand (examples being Yabujin and 8485). Given that it takes 15-20 years for each new generation to come of age, the emergence of Y2K makes fairly good sense chronologically. But I think that concurrently there has been a similar but less apparent emergence of nostalgia for the 2010s, especially the early and middle parts of the decade. The year 2016 in particular gets a ton of attention in this vein, with some describing it as the last good year or the best year of their lives. As a matter of fact, I've noticed people pointing out this year online since 2021—a mere 5 years after it actually happened!

So if you agree with my concept on this, why do you think it is that the nostalgia has emerged faster? I'll provide my own theory which is the time warp that was collectively experienced due to the pandemic. 2020 wasn't just the beginning of a new decade, it was a new way of living. Even now, I feel "closer" to my 2020 self than that one was to my 2019 self (if that makes any sense lol). And in 2021, I remember waking up on new year's day and feeling like I was in a kind of afterlife. Never experienced that after any other year except 2020.
