Really isn't the first time something like this has come up before. The book A Clockwork Orange was written entirely in NADSAT, which after the first chapter you really understood the whole concept of it being a teenage slang.
I believe we all suffer from mob-mentality at times, and its those times where we have a chance for personal reflection that save us from the continued stupifying effects of it. The reason for it being so pervasive in this day in age is a direct result of the implementation of technology and the ruthless obsession for monetary gain. Constantly we are battered with media in many forms, and advertisements. Magazines, TV programs, pop-music, youtube, facebook, billboards, movies, etc are all forms of media that can contribute meaningful content, and yet the majority of it is used as a way to mislead, or garner interest for things of no value. Cell phones, and ipods are also great in moderation, yet can be devastatingly stupifying when used to much. It really doesn't take that much more to go too far either.
That said, humans as a species are not doomed at all. There are plenty of intelligent people banking on this sort of thing so they can further their own agendas and lifestyle at the expense of the stupid and ignorant. Darwinism isn't at all being subverted by this, only proliferating by it.
