This is where I find programmers who are comfortable with static languages struggle with dynamic languages. There is a lack of understanding and this is yet another language trying to fix something that isn't fundamentally broken.

I think it really depends what you're trying to do. There's definitely a class of problems where the impact of a runtime type error would be low. But there are plenty of other cases where you want to constrain what you or your users can do at compile time.
