I still occasionally make that auto-save mistake.

AI tools have caused me to trip up a few times too when I fail to notice how many changes haven’t been checked into git, and then the tool obliterates some of its work and a struggle ensues to partially revert (there are ways, both in git and in AI temporary files etc). It’s user error but it is also a new kind of occasional mistake I have to adapt to avoid. As with when auto-save started to become universal.
