I want to achieve an understanding of the basics without necessarily being able to be a productive programmer. I want to get a grasp of the underlying nature of computer science, not being able to mechanical write and parse code to solve certain problems. The big picture and underlying nature is what I'm looking for.

I agree that many people do not understand, they really only learnt how to mechanical use something. How much does the average person know about how one of our simplest tools work, the knife? What does it mean to cut something? What does the act of cutting accomplish? How does it work?

We all know how to use this particular tool. We think it is obvious, thus we do not contemplate it any further. But most of us have no idea what actually physically happens. We are ignorant of the underlying mechanisms for that we think we understand. We are quick to conclude that there is nothing more to learn here. But there is deep knowledge to be found in what might superficially appear to be simple and obvious.
