It is said that programming language is just a tool, so you shouldn't stick to any particular language, and be flexible.
Paradoxically this is the reason why I want to stick to particular modern language, such as Clojure.
As programming language is just a tool, I don't want to suffer from a tool originated problem, and if possible, I don't want to spend a lot of time to learn several languages.
Almost certainly, Clojure is one of the most modern languages, and it let me focus on solving problem.
