"Functional" Programming

This is a message is a public service announcement:

The operating system you are using is written in C.
The web browser you are using is written in C++.
The web server you are using is written in C.
The website you are using is written in PHP.

"Functional" Programming was useless in the MIT A.I. labs in the 80's and has remained that way to this day. 

Stop letting yourself be deluded by the programming charlatans.  If "functional" programming was actually functional, then people would actually make software using it.

Obvious Troll? There is lack of good libraries for all these functional programs.
Compare amount of libraries in LISP and amount of C libraries.(with LISP is written thirty years earlier then C)
The syntax of functional programs striving to be 'pure'/'without state' vs dirty/messy C illustrates there is conflict between usability and language design. Such crap would laughed off in C world, where any limitation is promptly disposed off, even if it requires inline assembly(And, i can't ever see inline assembly 'polluting' your precious Scheme/Haskell code)
