Are we close to reaching the lowest point in pop culture?

The dissemination of the Internet from this past decade pretty much broke down the "monocultural" aspect of pop culture. While I personally like the variety of music, movies, TV shows, and video games at our disposal, the 2020s will probably be harder for us to define as a result.

I don't think this is necessarily the case.  I think the 2020s to the 2010s will be what the 1930s were to the 1920s.

The 1930s were not a groundbreaking time for pop culture, but 1930-1945 still had a distinct culture that a lot of people nowadays don't talk about or remember.

I remember during the 2000s when people would complain about the 2000s not having an identity or how it was watered down 1990s culture, which is not true looking back. The 2000s had an identity. Yes the early 2000s were not all that different from the late 1990s. It is true that a decade is hard 2 define when we are living in it.

I think a lot of this is because it was a slow transition from '90s to '00s.  For certain decades, we can think of big years where enough changed all at once that it was clear a new era had arrived or was about to.  Years like 1963, 1980, 1992, and 2008 come to mind.  On the other hand, the 90s faded into the '00s much more slowly.  To me, it didn't feel like the '90s were completely gone until around 2006.  Friends lasted until 2004 for that matter.

I'll have to disagree with the 1930s there, the 1930s were pretty good for pop culture, they had more to offer than the 1920s and especially the 1940s.

Tbh, I feel as the mid 2010s and to some extent the early, was oozing with a singular cultural identity even if it was more artificial and online driven. I was would say the traditional mainstream fully shifted to being online at some point in early to mid 2010s and prior was a bit more inbetween.

I feel as though, lack of singular identity ironically applies to end of the mid 2000s to early 2010s, in the sense that both 2000s and incoming or early 2010s culture was transitioning to something, with a clear direction and identity, but not exactly fully realized, taken to extremes, or felt as distinct. This may have contributed to samey or vague pop cultural feeling regardless of changes and with things like nostalgia industry increasing quite a bit in a mainstream way, as possible result. I still find it hard to find a single set of stereotypical things that exclusively and instantly sum up that period as much as periods like the early 90s, mid 2010s, or Y2K era. 

In the late 2010s to the present, the lack of singular identity is there for a different reason, as it doesn't seem like we have something we are in transitioning towards, other than holding onto and phasing out things that first started in the mid 2010s, undoing negativity of trump era politics and surviving and solving Covid. We haven't even explored the latter half of 90s nostalgia yet and there don't seem to be any breakthroughs like a new kind of technology or phase of something or very visible new era aesthetics, like you typically see towards the ends and beginnings of decades. 

I think prior to that the last pure singular cultural era was actually the late Y2K era to some point in the mid 2000s, it felt like everyone was following the same trends with some fringe groups ex. rappers, punks, emos, skaters, goths etc. The internet did not have overwhelming presence in replacing things, even though it had to a large extent the same effect it has today of easy access to info, exposure to fringe hobbies, mp3s etc . However radio, tv news etc were still the go to source and people thing felt very much controlled by the narrow stream defined by traditional media. Espically in a year like 2000 or 2003 with people aggressively following trends, worshiping or only listening to top 40 radio, awaiting the latest episode of charmed, survivor, south park or jackass to videotape etc. 

The last pre-internet and most authentic singular culture identity was the late 90s and to some extent the early Y2K era.
