Same here, I never understood Java interfaces, abstract classes, and a ton of other "features" but picking up Clojure was a breeze. I don't understand why complicating thing that supposed to be simple helps you by any mean. On the top of that, I have seen several cases when Java programmers tipped over in their own code because of the complexity that they thought they understand, except there was a particular case when it was doing something else then expected. Reasoning about Clojure (LISP) code is always easy because if you follow best practices you have small functions with very little context to understand. On the top of these, I see the ratio of LOC 50:1 (worst case even higher) for Java : Clojure code that does the same thing. Usually people get triggered and say why does it matter, but in reality less code is better for everybody. Easier to understand, less chance of errors, etc. Correctness was long time lost for majority of Java developers, just put out a survey and you can see it for yourself. It is also pretty common practice not to handle exceptions well and just let a DNS not found error explode as an IOexception and good luck tracking down what caused it (literary happened to me). I understand that the average Java dev does not see any value in LISP (Clojure) but it silly to expect that the average of any group is going to lead the scientific advancement of any field including computer science. One tendency that you can see if you are walking around with open eyes that the people who spent significant time in developing procedural code in an imperative language understand the importance of functional language features and the power of LISP. One can pretend it does not matter see you in 5-10 years and see how much this changes. twitter.com/id_aa_carmack/status/577877… youtube.com/watch?v=8X69_42Mj-g youtube.com/watch?v=P76Vbsk_3J0
