Functional programming island mentality

Island mentality refers to the notion of isolated communities perceiving themselves as superior or exceptional to the rest of the world. This term does not directly refer to a geographically confined society, but to the cultural, moral, or ideological superiority of a community lacking social exposure. Island mentality can be characterized by narrow-mindedness, ignorance, or outright hostility towards any artifact (concept, ideology, lifestyle choice, art form, etc.) originating from outside of the geographic area inhabited by the society.

Great C++ programmers look down upon the plebes of C++, just as users of greater programming languages look down on the peak of the C++ heap.

It's islands all the way down.
