The mid-late 2010s established many facets of daily life that we take for granted nowadays.
TL;DR: a bunch of timeless technology became popular/ubiquitous in the mid-late 2010s which will probably define the rest of the century and possibly beyond
I find it peculiar how most users believe 2000 or 2005 and onward is exactly the same or that 2020 obliterated everything 2010s overnight, when 2020 was largely the product of mid-late 2010s trends.
I believe that the "stagnation" truly began sometime during the mid-late 2010s. Put down your pitchforks, let me explain. I don't mean it in a negative way. What I mean is that we're going back to the status quo where change is gradual rather than every decade being a distinct historical period.
A rectangle that does stuff when you touch it, an app that lets you watch TV shows and movies instantly, an app that shows you short videos when you scroll up. I don't think these things are going anywhere (well, at least the first two), they're timeless and convenient. They more or less functioned/looked the same in 2016, and while they will improve, no doubt about that, I believe they'll continue to function and look similarly in 2036 and beyond.
And the concepts for them existed long before the 2010s. I don't think brain-computer interfaces and wearable tech will replace smartphones and tablets, they're too intrusive and/or inconvenient.
By 2014, smartphones were ubiquitous, short-form content was popularized by Snapchat and Vine, and streaming services were mainstream. And streaming services were the standard by 2017.
Yet I see people act like short-form content, engagement-based algorithms, and streaming services didn't exist before COVID, when by late 2019 the streaming wars had begun with the launch of Disney+ and TikTok was a mainstream app. Old Town Road topped the Billboard charts because it was popular on TikTok. It was even the 7th most downloaded app of the 2010s, despite releasing at the tail end of the decade.
Last but not least, I also see a bunch of people blaming COVID for declining test scores and a rise in polarization, but these trends were already present much earlier.
Test scores actually began declining in 2013, not 2020, and polarization has honestly always been a thing, but the contemporary culture wars were already heating up by 2014 with stuff like GamerGate and further escalated by the 2016 election.
