Sites like HN and Reddit tend to have a vocal crowd who decide that certain languages and tools are the domain of the elite. This groupthink is religiously defended through self-righteous blog posts ("I switched from Java to C and became a better person!!!") and comment threads. Inevitably, posters go looking for something that the True Language is known to do well, and then overgeneralize their experience. The result? Karma, and another voice to add to the constant din of Conventional Wisdom. Intellectual honesty takes a backseat to conformity...as usual.
Developers looking to improve their skills should pick up new languages, especially those of different paradigms and abstraction levels. But the hegemony of 'superior' languages will always weigh in to these decisions, and potentially block out the idea that the language is merely a tool used in implementing the final solution. It was never the end goal.
Nor is being right on the Internet. This phenomenon is one of humans, and their politicization of engineering. We must be wary of the ego, and harness it for it's good uses, rather than always looking to appear badass or hip through our technologies.
