Worth Using Emacs Without Knowing Emacs-Lisp?fleeting
I believe not. Emacs does not shine with its wonderful UI and I think it is not even a good ihm.
So, using emacs without the whole power of emacs-lisp that allows emacs to become whatever tool you need it to be does not seem to me like a goal one should want to achieve.
On the other hand, there are tools like doom or spacemacs that appears to prove me wrong.
