Emacs lisp is actually a very practical, easy to use and fun lisp to do a lot of great work in.
Richard Matthew Stallman notes:
It was Bernie Greenberg, who discovered that it was (2). He wrote a version of Emacs in Multics MacLisp, and he wrote his commands in MacLisp in a straightforward fashion. The editor itself was written entirely in Lisp. Multics Emacs proved to be a great success — programming new editing commands was so convenient that even the secretaries in his office started learning how to use it. They used a manual someone had written which showed how to extend Emacs, but didn't say it was a programming. So the secretaries, who believed they couldn't do programming, weren't scared off. They read the manual, discovered they could do useful things and they learned to program.

Of course if secretaries and regular office people with no prior exposure to programming or STEM education can program Emacs using Emacs Lisp and do useful productive stuff. Programmers most certainly can.
