No claiming that complexity is _subjective_ is dismissive. there is complexity and there is simplicity. There is also perceived complexity and perceived simplicity. As far as languages go Scala is pretty darn simple. There is very little going on in the background and the core of the language was designed to be a small set of orthogonal features that can be layered to build complex pieces of software. The perceived complexity is something we can argue about as it is subjective which is why you need to take a look at what your doing and how you might alter your practices to make it a more readable and simple implementation. You will always run across bits of a language that you will not understand, that doesn't mean the absolute state of the language has changed just your perception has changed.

This happens every time new developers run across a piece of Object Oriented C code with run time function overloading, their default reaction is I don't know whats going on this is too complex. C didn't magically become a more complex language because we introduced a new guy to function pointers and dynamic dispatch. Likewise Scala doesn't become more complex the first time you need to understand why marking your types as being covarient is important.
