"adoption of Lisp as a universal language" what a bad idea! I am occasionally an enthusiastic Lisp programmer (and I wrote 2 Springer-Verlag Lisp books many years ago), but I would never advocate that any Lisp be a universal programming language.

For most programmers, they probably need at least either Java or C#, a scripting language (Ruby, Perl, or Python), and a Lisp language (Clojure, Common Lisp, or a Scheme implementation).
