The article highlights that the real value of the ZK method is in the discovery of the deeper connections that run between ideas that on the surface may appear unrelated.

I can see how that could be useful in contexts where the work is about mulling over concepts, trying to uncover some hidden patterns. Philosophy, sociology, psychology come to mind. But looking at my large cache of notes on well known technology, I have a hard time seeing where the value would be.

I think it's worth pointing out because ZK pops up quite often on HN, as if it's the pinnacle of note taking. In reality, a lot of people here may just be wasting much of their time.
