Why? Most of the contents of these papers have made their way into books and programming languages. There's nothing wrong with getting it from a secondary source.
I find that reading primary sources reminds me that I can be a primary source. It reminds me that these ideas that I rely on were thought up by people, not handed down from Mt. Olympus.
The historian in me is also just fascinated to see the source of an idea that has made a large impact.
