Linux.com

It was invented by Dennis Richie, one of the most brilliant men in software, and was good enough for Ken Thompson, Bill Joy, Richard Stallman, and Linus Torvalds.

Actually, Richard Stallman's favorite language is LISP; though he writes in C for speed-dependent stuff. Emacs is an example, the core is written in C but much of the editor is written in RMS's own version of LISP, which makes it customizable by the end user. Bill Joy of course invented the C-Shell's not-extremely C-like really script language, though it is inferior to the Bourne shell for scripting. (It has some great user-interface features though.) The inventors of Unix specifically made it easy to script because of all of the little utilities such as sed and awk which contribute to that. Perl is just a condensed version of the Unix scripting toolkit in one language.

All software should be written in C.

All software should be written in whatever works best.
