I think your memory might be failing on this, because we’re about the same age and autosave wasn’t really a common feature in the 90s. MacOS didn’t introduce autosave until OSX Lion in 2010, and Microsoft’s auto-recover (which was their only feature even close to autosave until office365) wasn’t introduced until the 2000s and didn’t work properly until 2007.
It’s what the English call a bachelorette party apparently.
