Is there a dark side to this? A lot of the "not invented here" and chasing the latest tech could be caused by workplaces not realizing that there are less breaking ways to learn new things. Agile is great at this, by encouraging self-review at all levels. Then there's getting from sufficient to masterful at all sorts of general skills such as testing, version control, refactoring, requirements gathering, presenting etc. But to advance quickly in any of these you need mentors rather than self-study, because it's easier to learn directly from someone who has done it before and who can show you examples in the work context you already know.
