This article's "philosophy of Emacs" runs counter to the conventional wisdom that "Emacs is a good operating system, it just needs a decent text editor". If anything what the author describes is a "philosophy of Acme" -- do as much as possible by piping in and out of external processes. While Emacs can do this, there is no guiding principle to favor it over elisp extensions.
I think the philosophy of Emacs, if it has one, is "maximum extensibility". Whether that be with elisp or external processes matters not.
