The essential building brick of programming is the function, simply because -- unlike the class/object -- it is also a perfectly valid basic building brick for a turing-complete axiomatization. Once you know this, you can [1] search for existing functions [2] compose new functions [3] and debug them, in order to solve the particular problem at hand. Is that what you learn at school? No. Never. At school, you will not do any deep sea fishing. You will only read about deep sea fishing. So, someone with a degree in deep sea fishing, is not a deep sea FISHERMAN at all. He is an avid deep sea fishing READER.
