Just out of curiosity I went to MITs OpenCourseWare and was looking aroudnw hen I found this piece of information.
"For example, Lisp has become a language of choice for operating-system shell languages and for extension languages for editors and computer-aided design systems."

This is very confusing or me, becuase I have heard form mutiple sources that one of the main implementations of Lisp was in the programming of robots and/or AI as well.
