Some context on why some 80's kids keep getting mistaken for GPT
So, when you got online, you pulled or copied or saved all your messages, drafted up what was...essentially an essay of a response — trying to anticipate follow up questions or points of confusion. You planned it ahead of time. You studied your ass off to equip yourself with knowledge in the hopes of getting some replies off the same day you read them (it sounds stupid now, but that was fucking incredible — send and receive a letter same day!? Eesh. I am getting old).
Also, because communication was fast, but our time was limited, it was more like faster letters at first than it was like texts. It was a horror to waste round trips on misunderstandings — the person you were collaborating with might only get online Wednesday afternoons. If you were ambiguous, you might waste a whole week of progress just by not being clear! So, we were explicit.
