I didn't realize anyone alive still remembers how to use that language. I tell my students that when they retire they might be the local expert in some technology that currently doesn't even exist. I don't know what that technology is. Neither do they. The answer, of course, is by learning the new technologies as they go on.
Many people have it in their head that one has to take a class in a subject to learn about it.
People seem to think that once one leaves school, learning stops and the application of that learning begins. Nothing could be further from the truth. In fact, it's just the opposite. The basic knowledge imparted by a degree program provides a framework that the student will have to fill out later on his or her own. The material I cover in my classes is largely irrelevant.
