Well to be honest, there's a lot of people with CS degrees that don't know the fundamentals of basic CS either. I know, it sounds crazy, but you'll frequently run into people who graduate from reasonably top notch schools and have never heard of simple things like ternary search trees or suffix arrays, or even state machines.

In my experience I find that nearly all practicing programmers simply don't know a lot of important basics about building software or even how a computer works.

Or much worse: have heard, can answer questions about them, and still can't code themselves out of a paper bag.

I think because of the simplicity and approachability of Rails, almost anyone can pick it up and build a functioning website.

Rails is a niche that has a low barrier to entry. I doubt you can write an article that says: High frequency trading is a ghetto.
