I understand his perspective. I dabbled in programming as a child and teen, and then was an advanced user, running Linux on my desktop for years. At the time I started actual programming, I knew what a 'for' loop was, but not how to write one in any language - even Bash. I didn't know what an array was, or say, the difference between C and C++, to say nothing of functional and object oriented concepts.
