This is a significant psychological point that comes up in a lot of different contexts (sales contexts, mostly). But in the programming language context, I think it's a symptom of the dysfunction that the vast majority of discussions are at a superficial level (code snippets and theoretical features) and have little to do with building real systems over time.
