There's some of that, but more often it's developers whose arguments are a year behind the frontier models or, just as common, they're dramatically overstating their abilities.

It's an inherent tension that every discipline has to wrestle with. The most experienced developers are in the best position to evaluate where LLMs are, but those who are the loudest about their own abilities generally aren't in this camp. Humility tends to come with experience, and arrogance tends to come with inexperience.
