I figured out a shorter answer: It’s a foreign language that I want to learn. All these smarty-pants through the decades knew it and I wanna feel as if I’m a part of an obscure club.
I always hated the language of mathematics – I never liked the symbols, but I do like doing formulas in Excel, and writing algorithms (little machines) that make stuff happen.
This is like building a language machine. One of the things people say about it is
“Lisp is a programmable programming language.”
That intrigues me.
