I use Lisp whenever I can. I think most people who have been initiated into thinking in Lisp would prefer to use it over other languages in most circumstances. Many recent languages have grown to accommodate Lisp thinking in differently branded packages for this reason. It is fair to view Lisp as the ultimate high-level language that will persist as other languages come and go. The main reason is its ability to process itself. That's a key innovation that makes it more than just another programming language. There are programming languages, and then there is Lisp.
