I've been wondering about Auto Save for a while now

What’s the point of this autosave nonsense if most of the time it doesn’t recover anything?!
It keeps messing up operations, and when the editor crashes and says it will recover unsaved files, the result is this thing that only serves to irritate the user!

It’s either garbage, a useless tool, or I don’t know how to use it!

If anyone can enlighten me, I’d appreciate it!
