From calculator to computer

Kelly McNeill writes “It seems as if using computers from the command line is considered “advanced” and only gets taught at higher levels of education. I disagree. I believe that the command line should be the first interface that a user encounters. The first thing a user should learn is “ls” because that way they will learn what a filesystem is. They will learn how to organize their files. They will learn how to pipe programs together into powerful commands.”
