>I code in Emacs almost every day. I read and write e-mail in Emacs almost every day. I take notes in Emacs almost every day. I maninpulate data in Emacs almost every day. Yet I don't know LISP (any LISP!) at all

As others have said, it's never too late to learn.

My life has been within Emacs for 31 years. Yet I would say that I only really learned Elisp in the past ten years. Still at a tyro level, but enough to write my own functions for VM (I don't think mu4e existed when I started using it, also 31 years ago).

>Anyway, the most important part is: Despite all of this, Emacs is still fantastic for me! Here's to the next 50!

Amen.
