The word "Clojure" is strangely missing from the article. Does the author know about it? Of course, that is not to say that Clojure is a silver bullet, but it does address some of the issues he describes.
Besides, I don't think you can write an article about the state of modern lisp without mentioning Clojure.
I thought that was a strange omission at first too, but looking again, the article's from 2007, and Clojure didn't really become a thing that people knew about and used before mid-2008 or so (and it really took off in 2009).
Agreed. For example on pattern matching it's arguably the leader. But it's weak on others, like first class environments.
