The quote does seem to explain why I now see many engineers turning first to blog posts rather than official documentation for projects, ignoring the experience of more senior team members, and diving into half-baked designs rather than thinking in advance about possible pitfalls.

So maybe overapplied Agile is also a generational phenomenon [or maybe there's just a meta-eternal-September when prior generations realize it's eternal Septembers all the way down and every generation makes the same mistakes]
