I feel like maybe around 2012 the whole concept of eras died.
Like I can clearly visualize items/people/media from the 60s/70s/80s/90s/00’s, but everything is homogenized now and there’s really no “style of the time” either. I think everything from 2013+ will just be remembered as a malaise era, if anything. Maybe the style of the 2050’s will be post cyberpunk apocalyptic? I have no idea.
Im not even that old. And I still recognized it like you did.
A huge part of it is likely just tech. Tech plateaud around 2010 ish, 99% of things a normal person does with computers could be done fine on a 2010 computer (if sites weren’t total bogged java slop now which is just dev laziness but anyway)
