Once upon a time, I accidentally created a folder named “~” in my home folder (the company provided scripting framework would inconsistently expand variables, so the folder had a ton of stuff inside it).
I ran “rm -rf ~” and only panicked when I started to wonder why it wasn’t taking too long.
Good news is that it only managed to get halfway through my local checkout of aosp before I stopped it. Bad news was that it nuked most of my dotfiles.
Wikipedia thankfully links events by year: 664 BC, 663 BC
From peeking though the linked events, I’m going to say no, they did not notice at all.
