There is one other undeniable advantage to dynamic languages: you can express things in a dynamic language that you can't in a static one. Static languages try to be as sound as possible, at the cost of some completeness. Dynamic languages are less concerned with soundness and can be more complete. They are both "limited" to being Turing complete and therefore should be able to express the same things. Implementing the same algorithm can be cumbersome with types at times (No 1:1 representation of JSON Objects for example) but you can define types which wrap things like that to make it work anyway.
