I think
WIC is great--very enjoyable--and agree with this article that its presentation is basically a work of art, but it fails to explain "this is what code is," especially for the layperson.
Before reading this article I reflexively sent it to my wife, thinking that WIC will clarify what it is I do for a living. WIC does that remarkably in explaining what it is like to be a programmer. It tackles the business side of things, the current trends, and some history. But it is much less successful, when it comes to explaining the code.
An example of where it fails in explaining code to the layperson is the part about compiling C code in the command line. Yes, a layperson could follow this step by step, but I think if they did they wouldn't be able to put it in a larger context. Ok, it is compiled but what does that mean? How does that compare to other languages? These are questions that are left unanswered for laypeople, so it is just confusing and unrewarding.
For me as a professional dev, I enjoyed that part, especially because I could relate to it: it is like finding a basic tutorial on line, starting from scratch and following it line by line, something I do all the time. WIC is an excellent insider piece that really captures the zeitgeist of programming. The question should be reframed. If you really want to know "What is code?" you should read Petzold's Code. Any layperson could read it. You would have to work but it rewards. What is Code is better at answering "What does it mean to be a coder right now?
