The article explores Emacs's core architecture, revealing it's fundamentally a Lisp runtime built in C, not merely an editor. It discusses the historical reasons for embedding an Elisp interpreter, stemming from TECO macros in the 1970s, and why this design creates a deeply customizable, enduring tool that users find hard to abandon.
Background
