This is part of the modern fundamentals of the liberal arts: trivium, quadrivium, then everyone should also know how to physically use a computer (desktop/laptop and tablet variants), know how to make a document/make a spreadsheet/use the internet, know some HTML, know how to run a business, know how to do your taxes (without killing yourself), know when to contact an attorney (as important as 911 these days), and know how to change a tire.
These are BASIC skills... and at this point you are smarter than a fifth grader!
