I know the people behind Emacs like to think the system as usable out-of-the-box but I think selling it like that is ultimately a disservice b/c people end up underwhelmed and frustrated - never taking the time to learn ELisp. (the Emacs intro/tutorial is just a "welcome to this nano with annoying keybindings") I actually would challenge anyone to find someone who loves emacs and doesn't know a bit of ELisp :)
Ultimately ELisp is really not that much work to learn - but the root issue seems to me that ELisp isn't really a general purpose programming language and who wants to invest in learning a language you can't use outside of your editor? It's basically a DSL for a managing text and buffers.. It'd be way sexier to learn if it was a Racket or something
I also wrote a little annotated config intro (these are kinda more personal notes for my org/git/C++ workflow). It's a little terse and to the point and isn't trying to sell Emacs, but unlike most guides I tried to document what each lines in the config really means and help the reader learn how Emacs helps you discover more of Elisp as you go. https://geokon-gh.github.io/.emacs.d/ Maybe someone will find it useful! (I'm by no means an emacs expert or Lisp guru.. so if there are problems, let me know please :) )
