I quite like this. It’s the annual Beloit College (US) Mindset List. A list of cultural touchstones that have shaped the minds of the latest batch of students in the US and a gentle reminder that frames of reference change.
Could be done better though I suspect. Here’s my selection from their selection…

They have never used a card catalog to find a book.
Margaret Thatcher has always been a former prime minister.
Salsa has always outsold ketchup.
Tattoos have always been very chic and highly visible.
Rap music has always been main stream.
The KGB has never officially existed.
Text has always been hyper.
They have never had to “shake down” an oral thermometer.
They have never understood the meaning of R.S.V.P.
American students have always lived anxiously with high-stakes educational testing.
The European Union has always existed.
McDonald’s has always been serving Happy Meals in China.
There has always been a Cartoon Network.
The nation’s key economic indicator has always been the Gross Domestic Product (GDP).
They have always been able to read books on an electronic screen.
Women have always outnumbered men in college.
We have always watched wars, coups, and police arrests unfold on television in real time.
Belarus, Moldova, Ukraine, Uzbekistan, Armenia, Latvia, Georgia, Lithuania, and Estonia have always been independent nations.
Someone has always been asking: “Was Iraq worth a war?”
Most communities have always had a mega-church.
CDs have never been sold in cardboard packaging.
NATO has always been looking for a role.
Conflict in Northern Ireland has always been slowly winding down.
Nobody has ever responded to “Help, I’ve fallen and I can’t get up.”
