People get really defensive when I point out that they are proud of the things that they don’t know. Willful ignorance and anti-intellectualism is a cancer in anything it infiltrates and SWE is no different.
And I thought to myself that the most memorable parts of my career, the most rewarding parts, were when I took some task that was too hard for me, then, with great effort, became a developer for whom that task was no longer too hard for me.
You can use these to help you learn but, at least if you're a developer, letting it stunt your growth seems like a mistake.
