Now, I'm not an expert into pilots statistics, so my example might be off, but I do see a worrisome pattern in my daily work (software engineering). Blind reliance on those "frameworks".

Which isn't bad in itself, but no-one really knows how they work anymore. They just assume. And that leads to lots of cargo cults. Which ranges from inefficient to outright dangerous.
