Back in the 90s, that feeling when Netscape or Windows used to crash. First, a feeling of utter sadness, having lost whatever work was open (imagine writing a Word document for school and hours lost, that's when you learn to save regularly). Then the feeling of relief: ah, at least I gotta start over. But it keeps gnawing. What did I miss? Back then, there was no term for it (or it wasn't popularized), now there is: FOMO.
With regards to your quote, writing down helps the brain memorizing. It turns out typing it out doesn't help as much. In that sense, a notes app isn't akin to writing a note, the former isn't handwriting and the latter isn't digitized with all the advantages (and disadvantages!) attached. Its why I bought a reMarkable 2 for my mother (before they went all cloudy). She writes down a lot. It became a mess of notes, pure chaos. A digital notebook is the best of both worlds.
Sure, that was a lesson I learned from such (though some software did/does not allow to save). Even auto saved 'lagged' behind back then. Even 5 minutes can be a big difference if you made changes but can't memorize all of them. Nowadays, even fast software such as Sublime Text autosaves somewhere in homedir.
Back in the 1990s, on old Macs, when Netscape crashed, it crashed with a "type 11" error which brought down the whole system. (I remember Word had autosave... I don't know when it first appeared, though.)
I have the same feeling now... Firefox doesn't crash anymore, even with 1000+ (unloaded) tabs... but I will often found that the page (or a youtube video) is now gone/removed after months or even years.
I suspect it still loses data and maybe corrupts profile if there is a disk full.
It deletes history entries once they're too old, and it also only keeps the last timestamp of when a URL was visited, so you can't know how often you visit a URL.
