I feel like the 2010s are the first decade in 100 years that doesn't have a recognizable aesthetic or vibe.
Every decade since the Roaring Twenties had its own recognizable culture, visual aesthetic, music and so on. In the 2010s, the Internet allowed us to become cultural omnivores. It's good that everybody had access to whatever niche subculture they enjoy but it also meant that there was no more monoculture that we all shared.
For US pop culture, it makes a lot more sense to demarcate based on presidential terms. So 1981-1985, 1993-1997, 2009-2013. I've noticed this with 1989-1992, which has a very particular vibe (watch the intro to Saved by the Bell or Do the Bartman to see what I mean) and which just so happened to be Bush Sr. term.
