Contrary to what I read on social media and in the mainstream press, when I think of the average software developer, I don't think of someone "moving fast and breaking things" in a cutting-edge tech start-up. I think of someone working in an established business on legacy systems that end users have come to rely on. Because that's what the vast majority of us actually do. Most software developers are in the distinctly not-cutting-edge business of keeping the proverbial lights on.
