&gt; Surely that has nothing to do with Java being 20 years old, and Clojure 1.0 being 6 years old?<p>Lisp has been around for 50+ years, hasn&#x27;t really helped its popularity much. But I&#x27;m willing to bet with you that in 14 years from now, Clojure will have even fewer users than it has today.<p>&gt; &gt; Clojure doesn&#x27;t even win in the one line department against modern JVM languages (e.g. Kotlin).<p>&gt; Example, please.<p>Here it is in Kotlin:<p><pre><code>    (0 .. 20).filter { it % 2 == 0 }</code></pre>
