I think it is a matter of how you are exposed to programming. I started with pascal at 9, and I wrote my first (VM-)bootable OS in junior high school (around the age of 14). Not as fancy as this of course, but it booted into an environment not unlike r4rs scheme - based on SIOD. A scheme error was handled but any C errors would immediately lead to a kernel panic. I am not a programmer today, but I can still wrap most of my head around many low level concepts. I can't, however, write anything resembling a modern web page. Nor can I understand how any larger JS application works.
