With UNIX, the integration platform is the shell, hooking simple specialized tools through pipes and the shell language.
With Emacs, the integration platform is a Lisp environment, hooking specialized Lisp tools and Unix tools through Emacs buffers (or buffers regions) using the Elisp language.
So it's an extra layer, but if you look at it in this way you can see similarities: an environment that makes it easy to compose elementary functions into an integrated whole.
In both cases, it's most suited for people who are ready and willing to build their own specialized environment on top of a powerful platform. Although many users don't and stick to the basics too.
