> You haven't cut away abstraction, you've changed to a different kind of abstraction. Yes, Linux depends upon abstractions. Everything in computing is an abstraction, including those 1's and 0's that tell the processor what to do. (Anything below that is electrical engineering.) The differentiators are the complexity and stability of that abstraction. When people talk about "everything being a file", they are referring to lower level abstractions that are relatively simple and stable. Likewise, when people talk about HTML/CSS/JS they are referring to lower level abstractions that are relatively simple and stable. This is less true (sometimes significantly less true) when people start discussing frameworks/libraries, whether that's in Linux or web development.
