Who wants in? We can talk about what is was like to write a letter to your grandma or having no other way to ask someone out other than by calling them on the phone. Or checking out movies at Blockbuster or whatever your national equivalent was (we usually checked out videos at the grocery store, actually).
We’re cool because we can actually remember the USSR and “East” Germany. Although not as cool, I can remember when homophobia and transphobia was so much more widely accepted and the “default” position for most Americans. Not as cool.
I'm not quite all the way to 40, but I do remember a time before anyone in my family owned a computer. And when asking a child in school "Have you ever used the internet?" had two correct answers: "Yes." and "No.", whereas today there is only one correct answer, which is a very concerned sounding "Are you OK? Do you need me to call someone?". I dropped my first cell phone - which I got when I turned 14 - from a third floor window unto pavement. It was fine. Or, well, it couldn't save any text messages since I already had like 60 of them that I hadn't manually deleted, so the hard drive was full, but actually damaging it physically would have required a commitment to total war by a major industrial state.
