Not really relevant, but: word processors were just starting to be used when I went to college, but I still mostly preferred using my portable electric typewriter. During my junior year the G key broke off and disappeared, so all my papers from that point on have the Gs written in by hand. If they ever invent time travel, I'm going to assume that enough other people are going back to kill baby Hitler and I'll slap the shit out of 20-year-old me.

And so damn infuriating when you need them forty years later lol. I'm currently in the middle of some really obscure maths at work and my only reference is a hand typed paper from 1983 with super critial plots on it, but it's all been scanned in and put online at the lowest possible resolution. It's torture!
