Eh as a college professor something has changed, not just the population. My experiences parallel the GP. I noticed it first with filename conventions; it rapidly changed from there.

This is in the same population of students. I noticed basically that IO tasks were eating up an increasingly big fraction of effort and time early on in courses, reflecting problems that didn't exist previously.

This seems to be for the reasons stated, that file IO stuff is being abstracted away. What used to be typical necessary computer fluency is now "low level" for many.
