I grew up in the 90s and I remember being able to truncate the year down to just 2 numbers when talking about years within the current millennium. It seems like we’re still saying twenty before every year and I’m just wondering when that will change.
In the 30s you can start talking about the 20s. It will be annoying at first because people will try to be funny and/or get intentionally get confused that you’re talking about the 1920s.
I’d imagine talking the way you’re being nostalgic about will be in full swing by the 2040s.
