To say it shortly: the biggest difference between so called static and dynamic languages is that the latter’s programmers spend most of their time arguing on how superior their language is, and the former’s ones just write code.

There is plenty of Java and C# code just begging to be used, free libraries for nearly every task on earth while most software libraries written for dynamic languages fall into the category which some people call advocacyware (that is, software that crippled that it’s plain unusable and the only purpose of its existence is to be mentioned in advocacy arguments, as in “of course, common lisp can do threads portably”).
