Regarding computer literacy, there are two glaring difference between the current generation and the one who grew with computers in the 90s: one is the one you mention; in the 90s we were our own tech support, so to speak, and when DOS didn't want to run that shiny game that you just got, it was up to you to figure out the problem and hopefully to find a solution. We learned a lot because we had to.
The other is that most devices are increasingly more geared towards conmsumption and less towards experimentation and creation. On one hand, I used to do crazy things with assembler, regarding direct access to ports and interrupts, that no current OS would allow. On the other, the shift towards phones has greatly changed (and IMHO, reduced, mostly) what we do with our computers.
The good news is that the info is out there for the ones who do want to learn; we didn't have that privilege. Still, these are a minority, and in my experience, the average 18yo person preparing right now to start a degree in CS (or whichever career centered around programming) knows way less about computer than what we used to know at their age.
