GGP's claim is emacs is better learned as a lisp machine than a text editor, which is akin to saying a monad is just a monoid in the category of endofunctors. In other words, it does a neophyte no good to see the matrix without having lived in it first. It's all one can manage learning emacs's editing primitives if you've never seen it before. Reminding them some (but not all!) of these primitives are in fact elisp expressions is just annoying.
I have not forgotten my own "beginner's journey" - au contraire - I vividly remember it, and thus I'm sharing an admonition - so people wouldn't waste their time. Because I did. Besides, I have successfully mentored people from zero-to-hero and helped them learn Emacs.
My suggestion to focus on Elisp is not like tech-splaining monads, and Lisp is not that difficult. Definitely not even in the same league of difficulty as Haskell. It is an astoundingly simple language. And yet people just ignore it for years, clueless of what they're missing.
