There are self-confident young people who think of others as idiots:

"Get illiterate children who did not learn computer science"

Let you know, you are our literate, that a decade ago computer science in many schools of many cities was not in principle, in universities taught anything but not the use of word, and a person may not know the elementary things in your field, but be a great specialist in their own.
Not knowing is not shameful - it is shameful not to ask.
