> Can you feel the energy of a software industry eager to break free from the low-trust environments we’ve grown used to?

I beg your pardon, but Scrum did not fail because "it does not work", it fails because low-trust environment won't make room for an agile mindset. An I really hate the term "agile mindset", because it is overused. But if you give people responsibility and accountability, you can get a powerful, creative environment. Which, in turn, means that you need less management. Interestingly enough, middle management is usually not happy about that - so Scrum fails.
