It seems obvious to us, but computer literacy in out country (and the world) is quite low. I think this underlines how bad it is. Can you imagine if the English literacy rate were only a few %? It wouldn't be uncommon to hear of people doing strange things since they wouldn't be able to read warning signs.
In this case, I think it's probably because most librarians can't read, or at least many in publicly funded libraries. It's hard to point to one illiterate librarian when their colleagues are also illiterate.

I am genuinely trying to determine if this is a joke. :) People already do confuse those! I have unfortunately seen many arguments on Facebook over the correct usage.
This is pretty much almost already the case for mathematics; understanding of basic mathematical concepts in the general public is piss poor. No one is up in arms about that.
