I mostly don’t care how popular Lisp is. I am not using Lisp in order to score better in a popularity contest. I am using Lisp because it is the best programming language I know for the kind of programs I write. I don’t think there is anything particularly or seriously wrong with Lisp. It might be that at the moment it does not provide what some people have come to expect from a programming language (free cross-platform implementation with all the libraries you could possibly want). Whether this will ever happen, I don’t know, and I don’t care (though I respect that others might). I do think I know that some of the people who want this to happen will have to get their hands dirty and just do it. No amount of lamenting is going to magically create any libraries. — What is wrong with Lisp?
