You make a great point, and I think Lisp has enough fundamental value to deserve its place as the "100-year language". In 2060, people will still be using some descendant of Lisp. On the other hand, I think some aspects of CL are outmoded. I don't like the lack of support for maps as a top-level structure, and equality in CL is seriously broken, IMO. I'd prefer to code in CL over Java/Blub, but I prefer Clojure over CL, and probably Haskell or ML over Clojure. (Lisp has better syntax, and macros are very cool, but static typing wins for large projects, in my opinion.)
