What I think is shocking is that 99% of the software engineering world these days would have zero ability to comprehend this explanation. In my opinion, you could not be a real programmer without the ability to understand what your program is under the hood. You might be able to get away with it, but you're just faking it.

And yet, 99% of the people I've ever seen in the industry have no idea how any of the code they write works.

I used to ask a simple interview question, I wanted to see if potential hires could explain what a pointer or memory was. Few ever could.
