We all use abstractions, and abstractions, good as they are to fight complexity, are also bad because sometimes they hide details we need to know. In other words, we don't genuinely understand anything. We're parrots of abstractions invented elsewhere and not fully grokked. In a company there is no single human who understands everything, it's a patchwork of partial understandings coupled functionally together. Even a medium sized git repo suffers from the same issue - nobody understands it fully.

Wholeheartedly agree. Which is why the most valuable people in a company are those who can cross abstraction layers, vertically or horizontally, and reduce information loss from boundaries between abstractions.

Some executive: "That's nice, but what new feature have you shipped for me recently?"

Hey, you read my review!

Well, hopefully your developers are substantially more capable, able to clearly track the difference between your requests versus those of other stakeholders... And they don't get confused by overhearing their own voice repeating words from other people. :p
