Lisp languages are not even functional programming languages, they're mostly general purpose. Lisps are interesting for other reasons such as the s-expression syntax being similar to the AST, lists and other data structures as first class entities and so on. Also they are very practical languages. Clojure and Common Lisp are used in real world production systems for example. Missing out on lisp is missing out on a lot of interesting ideas.
