This is true, and I don't mean to trivialize the work of today's programmer.

However, I suppose somewhat subjectively in reviewing or writing any of this glue or logic layer code using modern web frameworks I've never had the sort of WOW response that I do when I see what the programmers of yore were coming up with.

If by "understand" you mean glue together all of the high-level abstractions of each of those domains, each of which have mountains of tutorials / blog posts / StackOveflow answers, then sure.

Thank you! This is exactly the kind of thing I was looking for.

It wasn't the one I saw previously, but it's a good starting point.

The fact that you keep referring to moment of inertia as "angular momentums" make me doubt that your story is true.
