Lisp. Lisp is the only language

Why there are other programming languages besides Lisp? With Lisp's macro system you can create any language you need ever. Small, big, finely tuned for your task. Supporting other languages means opposing progress and delaying the inevitable future. There should be only one language and myriad languages at the same time. The one language is Lisp.

I've seen complex Set Theory expressions, and I cant read them. Even simple Zermelo-Frenkel axioms look very scary, compared to LISP.
