I think modern "kids" (who now are in their early 40s perhaps!) don't quite get how useful the spacial finder was to non-technically aligned people. "I left it right here" is a huge piece of memory that our brains have developed over millennia, and the spacial finder played right into that.
The "it's in the directory listing in terminal" or "spotlight will find it" or "what is a file" don't really compare, even if they can be made usable.
Funnily enough, learning how to computer from Chromebooks and tablets have made modern kids incapable of understanding the spacial metaphor at all. Their navigation is entirely search-centric.
