Ohhh, I can sign off on this.

The amount of 20 year old university students that do not understand how to save a file to a specific location on their computer and then retrieve that file later has skyrocketed the last five years.

This is very obviously a consequence of them only ever having worked through tablet- or phone-type interfaces, where the file system is completely hidden to the user. I teach these people to program, and their eyes gloss over when I ask them where they put the data file they need to parse for the assignment. Once they understand the question they’ll typically open the file explorer, click on “recent files”, and ask me why their python script won’t open it, when the files are right there next to each other in “recent files”.
