There is a great post by Dan Abramov on his Overreacted blog that I really relate to and until I write my own “Things I Don’t Know” post I’m just writing down his words to have as a reminder for the future.
We can admit our knowledge gaps, may or may not feel like impostors, and still have deeply valuable expertise that takes years of hard work to develop.
First, there is often an unrealistic expectation that an experienced engineer knows every technology in their field. Have you seen a “learning roadmap” that consists of a hundred libraries and tools? It’s useful — but intimidating.
What’s more, no matter how experienced you get, you may still find yourself switching between feeling capable, inadequate (“Impostor syndrome”), and overconfident (“Dunning–Kruger effect”). It depends on your environment, job, personality, teammates, mental state, time of day, and so on.
Experienced developers sometimes open up about their insecurities to encourage beginners. But there’s a world of difference between a seasoned surgeon who still gets the jitters and a student holding their first scalpel!
Hearing how “we’re all junior developers” can be disheartening and sound like empty talk to the learners faced with an actual gap in knowledge. Feel-good confessions from well-intentioned practitioners like me can’t bridge it.
Still, even experienced engineers have many knowledge gaps. This post is about mine, and I encourage those who can afford similar vulnerability to share their own. But let’s not devalue our experience while we do that.
