What percentage of software churn is based on developers being reluctant to call out mistakes by other developers on their own teams/in their own companies (while having no problems calling out flaws in internet strangers' code)? 'Curating' what developers are allowed to do has been the focus of the last few jobs I've declined. "The guys at the other office are too dumb to learn (React|Angular|CSS|tech X). Obviously, we need a team to invent something that uses (React|Angular|CSS|tech X) behind the scenes but has a totally different API and no easily searchable documentation or support outside of our company." Tailwind looks like one of those escaping into the world, when telling your devs to pay attention to a style guide would have been the easier solution. Technology does not have a glorious track record in solving cultural issues.
