Dazed and Confused came out in 1993 and was based in 1976. 

A comparable movie today would be based in 2007

The reason that 1976 seems much more distant from 1993 than 2007 does from 2024 is that the internet has trapped us in a cultural forever-present, unable to move into the future because the things of the past never fade from sight. 

We inhabit a static, stuck, ersatz culture.

Interesting take, I'd say that most of these changes moved to the digital world.

The Internet AD 2024 looks totally different than AD 2007. There's different lingo, memes, social media. And we already experienced multitple waves, just like we had them in the physical world of fashion, music and culture in general. (picrel)
