I'll stop using Dunning-Kruger when it becomes irrelevant. And no, I don't consider myself any less prone to it than other people, that's when I've found it most useful. And Dunning-Kruger is not "attributing stupidity" (talk about a shallow take), it's actually most insidious among those who are experts in one field, hence they've spent so much time there they have zero experience in other specialized domains (again, something I've recognized as one of my biggest weaknesses; thanks Dunning-Kruger!)

In my experience, people who get offended by Dunning-Kruger don't even realize they are prime examples of it.
