I am in the same boat. And then with full text search, I wonder how much it is truly needed.

But, if I wanted to as a thought exercise, I wonder whether this is something like Claude Cowork could tackle. "Analyze these notes and attempt to map organic links between them" (obviously a real prompt would be far more nuanced and detailed). And see what it came up with. The nice thing about Obsidian is that it'd be really easy to clone your vault and let Claude play with the clone so you don't risk a mess.
