I think smartphones obscuring the filesystem away, and desktop search making the skill less of a requirement really hurt the filesystem understanding for younger generations.

I remember Steve Jobs saying the last area of complexity they needed to be solved was the filesystem, which is why they made the iPhone the way they did, with apps owning the files, so users didn’t have to deal with it. We’ve seen the Files app introduced and those walls get broken down, so it was clearly the wrong approach, especially when various apps can all perform actions on the same type of files.

Jobs also said death would take care of the problem of people not knowing how to type. I often think he should have taken the similar approach to the filesystem. Required learning for the modern era, not something to hide away so skills never develop.
