Roam Research's allure as a note-taking app comes from the ability to link notes together as a two-way link. This lets notetakers more closely model the human mind and encourage creativity and knowledge-based insight.
This reminds me of an early idea for the web, where some hyperlinks were meant to be two-way. Although that didn't reach fruition, it makes me wonder whether the one-way links achieve similar results.
That is, through the exabytes of knowledge on the web and billions of links between thoughts, ideas, and other content, has the web developed to become a knowledge graph of magnifiscent scale? A grand hive mind that captures the state of human consciousness? And by corollary, is creating, editing, deleting, or consuming web content participating in the largest Zettelkasten system in history?
My take is yes, to both.
