Computer languages are much simpler than human languages, and they also operate in similar kind of logical ways. I definitely remember how hard was to go from pascal to C to Cpp to Python to prolog to haskell to SQL... until at some point nothing was new.

To me, working with a computer language involves specific thinking, constructing stuff in my mind. But human language is nothing of the sort, though it's possible to kind of do the same if I sit down and try to polish a written sentence. But talking in, and understanding a conversation is as far from this as I can imagine. And the learning process is so extremely different.
