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.
No, not at all. It’s just easier to draw lines on where things start and stop once they change, so you may not feel like you’re “in” an era.
