You're right. And it's the adult version of "everybody gets a trophy" in that we all by default assume each other equally capable. Look at every single answer that pops up on the academic exchange forum - someone inevitably brings up impostor syndrome, almost no one, except in extreme cases, ever suggests that maybe someone is in the wrong field or in over their head.
Yes, but then again, Dunning-Krueger effect is quite real -- I've seen it.
And you know who never has to worry about Dunning-Krueger in a given field? Folks with "impostor syndrome" in that field.
Yes, it's possible that some folks with traits of impostor syndrome are genuinely incompetent and incapable of learning a given field, but much more likely that it's something the opposite of Dunning-Krueger at play. And as a software developer, I've seen many more genuinely incompetent people with Dunning-Krueger than I have genuinely incompetent people with imposter syndrome.
There's always the rare supremely-confident 10x developer, but as a general rule, people with no zero doubt in software development make me very nervous, because I've send it turn out badly much more than I've seen it turn out well.
